For more than a century, infantry units have fought under an unforgiving reality: When you’re humping a ruck through non-cooperative terrain and you run face-first into an entrenched bunker, fortified machine-gun nest or enemy light armor, your options for immediate heavy fire support are painfully thin.
You can’t drag a 70-ton M1 Abrams through every swamp or up every mountain, and waiting on close air support or artillery when rounds are actively snapping over your head is a luxury combat rarely affords. The Army needed a vehicle that could cast a wider net without encountering the logistical hurdles of other direct-fire weapon systems. Enter the M10 Booker.
If you talk to Army leadership or defense acquisition officials, they will aggressively correct you if you call it a “light tank,” insisting on the clunky moniker of “Mobile Protected Firepower” (MPF).
Unfortunately for the brass, my capacity for bureaucratic red tape is pretty much non-existent, so let’s just call a spade a spade: it has tracks, a turret, heavy armor plating, and a 105mm cannon.
That sounds like a light tank to me. Whatever label the Pentagon wants to slap on the data plate doesn’t really matter to the Jimmys and Joes; it is a dedicated combat vehicle built to roll into Hell alongside the infantry and smash whatever is in their way.
Don’t get it twisted: the Booker is not designed to replace the Abrams in a kinetic slugfest against enemy heavy armored formations. Instead, it aims to solve a glaring operational vulnerability that has plagued American forces for generations.
It was designed to take the cutting-edge fire-control systems, lethal optics, and four-man crew philosophy of our frontline armor and pack it into an agile, sub-40-ton platform that can deploy rapidly to any theater on the globe.
Underneath its composite armor lies a modern, aggressive solution to an old-school problem, thus ensuring that when our forces cross the line of departure into the contested battlefields of tomorrow, they bring the undisputed master of direct-fire support with them. Unfortunately for the Pentagon, none of that would be sufficient to save this project from being shelved for the foreseeable future.
Ghosts of Armor Past: Humble Beginnings
To understand how the M10 Booker ended up on the chopping block, you have to look at the long, troubled lineage of American light armor that paved the way for its demise, starting with the M551 Sheridan.
Born during the Cold War and baptized in the jungles of Vietnam, the Sheridan was the Army’s attempt to give airborne and light units an air-droppable, aluminum-hulled scout vehicle packing the direct-fire punch of a 152mm gun/launcher. On paper, it was a dream; on the battlefield, it was a nightmare.
Unfortunately for the crewmen inside, the paper-thin armor made it a death trap against basic rocket-propelled grenades and landmines, while the finicky, caseless-ammunition gun system choked and sputtered in humid, combat-stressed environments.
When the Sheridan was retired without a direct replacement in the late 1990s, it left a massive, bleeding capability gap in the airborne and light infantry communities. The Pentagon would then spend the next 30 years desperately trying, and repeatedly failing, to fill that gap.
Once the Sheridan was relegated to the history books, the Army attempted a modern band-aid during the Global War on Terror with the Stryker Mobile Gun System (MGS). Slapping a low-profile 105mm tank cannon onto an 8×8 wheeled chassis seemed like the ideal compromise to give Stryker brigades rapid direct-fire capability. In reality, the vehicle was an absolute mechanical disaster.
The violent recoil of the 105mm blast constantly battered the wheeled platform’s suspension and drivetrain, and the notoriously complex autoloader choked on sand, dust and carbon at the worst possible moments. On top of that, firing the gun over the side can potentially tip the platform over on uneven terrain.
Maintaining the Stryker MGS became an unsustainable logistical nightmare for unit mechanics, and crew survivability against modern threats was practically non-existent. By the time the Army officially pulled the plug on the MGS in 2021, the exact same tactical void that plagued the post-Sheridan era was wide open once again.
Determined not to repeat the fragile mistakes of the Sheridan or the wheeled compromises of the Stryker MGS, the Army launched the Mobile Protected Firepower (MPF) program. The goal seemed simple enough: build a rugged, tracked, direct-fire combat vehicle that could accompany light infantry into austere environments, survive real battlefield threats, and fit cleanly onto Air Force transport planes.
General Dynamics Land Systems secured the contract with a heavily modified Austrian-Spanish ASCOD chassis, eventually naming the platform the “M10 Booker” to honor WWII Medal of Honor recipient Pvt. Robert D. Booker and OIF Distinguished Service Cross recipient Staff Sgt. Stevon Booker.
Then, almost immediately, the classic curse of military acquisition set in. Requirements bloomed, composite armor was demanded, advanced active protection systems were needed, and heavier digital architectures were made a priority.
More requirements means more equipment, and more equipment means more weight. Serious weight. What started as an agile, expeditionary concept rapidly ballooned into a 42-ton heavyweight, planting the early seeds for the program’s eventual demise.
By the time the Booker was gearing up for fielding, the operational landscape had fundamentally changed underneath its tracks. The war in Ukraine and the explosion of cheap, lethal drone warfare forced the Pentagon to take a hard look at what it was actually buying. Spending millions of dollars on a 40+-ton manned vehicle that could no longer be dropped from a C-130 and barely fit into established strategic airlift was a tough pill to swallow.
On top of that, restrictive contractor maintenance agreements meant unit-level mechanics were pretty much locked out of fixing their own machines in the field. When Army leadership took an honest look at the shifting demands of Large Scale Combat Operations (LSCO), the math simply did not add up anymore. Rather than dumping billions into a platform that had strayed far from its original expeditionary purpose, the Army pulled the plug, choosing to pivot toward lighter, uncrewed, and truly mobile future technologies.
Breaking Down the Booker: Armament and Optics
The primary feather in the Booker’s cap was its ability to deliver heavy, organic direct-fire capability directly to light units, and on paper, it packed plenty of heat. Its primary weapon was the 105mm M35 rifled cannon. While it lacked the sheer kinetic energy of the Abrams’ 120mm smoothbore, it was plenty sufficient for its intended purpose.
It was never designed to duel frontline enemy main battle tanks head-on. The 105mm was optimized to crack open concrete bunkers, eliminate fortified anti-tank missile positions, and shred light armored vehicles like Russian BMPs or Chinese infantry fighting vehicles.
The real strength of the Booker’s lethality came down to its digital guts. The Army directly ported over the advanced Fire Control System architecture from the M1A2 SEPv3 Abrams. They then paired the cannon with high-definition, third-generation Forward Looking Infrared (FLIR) optics and the Safran PASEO Commander’s Independent Tactical Viewer (CITV).
This gave the four-man crew true hunter-killer capability, allowing the tank commander to acquire the next target while the gunner eliminated the current one.
Secondary armament mirrored standard American armor doctrine: an M240 7.62mm machine gun mounted coaxially next to the main gun, and Ol’ Reliable: the classic M2 .50 caliber heavy machine gun operated at the commander’s hatch.
Surviving the Modern Battlespace
To keep the vehicle within a manageable weight class, General Dynamics built the Booker around a welded-steel hull augmented with modular composite armor packages. The baseline protection was rated to defeat heavy machine gun fire, while the frontal armor could withstand hits from modern autocannons and artillery fragmentation.
Internally, it borrowed proven safety features from the heavy armor community, including isolated ammunition stowage with blowout panels and automated fire suppression systems to protect the crew from catastrophic secondary explosions.
Unfortunately, survivability is where the fundamental contradiction that is the M10 Booker began to unravel. It lacked the dense depleted uranium composite armor of the Abrams, which means it’s still extremely vulnerable to modern anti-tank guided missiles and top-attack loitering munitions.
The Army attempted to solve this drawback by designing it to carry modular active protection systems, but every bolt-on countermeasure and extra steel plate added more and more weight. Soon, the vehicle was caught in a trap: it had become too heavily armored to be a nimble, air-droppable asset, but remained too lightly protected to survive on a modern battlefield saturated with suicide drones and heavy kinetic munitions.
Locomotion and Strategic Anchors
Propelling a 40-ton vehicle requires a massive amount of reliable power, and for the Booker, the Army opted for a front-mounted MTU 800-horsepower diesel engine mated to an Allison automatic transmission and a modern hydropneumatic suspension.
Putting the engine block in the front served a dual purpose: it acted as an extra physical shield for the crew in the turret and delivered significantly better fuel economy than the thirsty AGT1500 gas turbine in the Abrams. Across rough dirt and semi-restricted terrain, the Booker was remarkably agile, hitting speeds around 40 to 45 mph without breaking a sweat.
The problem wasn’t tactical mobility in the dirt; it was strategic mobility in the air. The original light armor dream was an asset you could roll out the back of a C-130 or air-drop directly onto an objective. At over 80,000 pounds, the Booker completely killed that dream. While the Air Force could technically cram two Bookers inside a massive C-17 Globemaster III, moving an entire battalion required an absurd amount of dedicated heavy strategic airlift. For an expeditionary force that prides itself on packing light and moving fast, the Booker ended up being a 40-ton anchor attached to their logistics chain.
The Human Element: Man vs Machine
When designing modern light combat vehicles, almost every foreign power opted for an automated loading system. Russia and China went all in on autoloaders to keep their vehicles small, light, and manned by just three crewmen. General Dynamics and the U.S. Army took the opposite approach, sticking firmly to the traditional four-man layout: Tank Commander, Gunner, Loader and Driver.
Keeping a human loader in the turret was one of the smartest theoretical calls on the platform. Beyond slamming 105mm rounds into the breech in seconds without complex mechanical linkages failing in dusty environments, that fourth crew member is pure strategic gold in the field.
Operating an armored vehicle is brutal, exhausting manual labor. When a tank throws track in deep mud, blows a hydraulic line, or needs 36 straight hours of continuous perimeter security pulled, a three-man crew burns out rapidly. Having an extra set of hands, eyes, and ears would give Booker crews the operational endurance that foreign platforms simply cannot match.
The Global Matchup: Light Armor on the World Stage
When looking at where the Booker sits on the global chessboard, the debate immediately runs into a massive wall of doctrinal confusion. The media and casual defense observers constantly tried to pit the Booker against heavy frontline main battle tanks like Russia’s T-90 or China’s Type 99.
Frankly, that comparison completely misses the point. Asking a 40-ton vehicle with a 105mm gun to trade blows with a 125mm heavy tank in an open field is a suicide mission. The Booker was built as an assault gun meant to support dismounted infantry and crush light armor, not duel heavy armor head-on.
The Eastern Rival: China’s Type 15 (VT-5)
One of the most honest Booker comparisons you can make is with China’s Type 15 light tank. Purpose-built for the brutal, oxygen-deprived elevations of the Tibetan Plateau and amphibious island-hopping campaigns, the Type 15 represents the exact opposite design philosophy of the Booker.
The Chinese opted for an aggressive, low-profile 36-ton vehicle powered by a 1,000-horsepower diesel engine, an autoloader, and a three-man crew. By cutting out the fourth crew member and relying on automated loading mechanisms, the Type 15 achieved an exceptional power-to-weight ratio tailored for high-altitude mountainous warfare where heavy armor literally cannot breathe.
However, that smaller silhouette comes with steep trade-offs. The automated ammunition carousel creates the exact same vulnerability seen in Russian armor, where a single penetrating hit detonates the onboard ammo and gives the crew an all-expenses-paid trip to the Turret Toss Olympics. Furthermore, the lack of a fourth crew member makes field maintenance and long-duration operations in harsh environments an absolute nightmare for Chinese crews.
Doctrinal Identity Crisis
The real problem for the M10 Booker wasn’t how it stacked up against the Type 15 on a spec sheet, it was that the U.S. Army never fully figured out what it actually wanted the vehicle to be.
The Chinese built the Type 15 for specific, non-negotiable terrain where an Abrams or Type 99 simply cannot physically drive due to weight and altitude restrictions. The U.S. Army, on the other hand, tried to turn the Booker into a do-it-all hybrid. They wanted it light enough for airborne and light infantry divisions, but armored enough to survive heavy fire.
The idea was to make it cheap and simple to maintain, while also loading it with proprietary contractor systems. In trying to build a vehicle that could satisfy every branch of combat arms at once, the military produced a compromised machine that ended up pleasing almost no one.
Ground Truth and the Final Verdict
Stepping into the turret of an M10 Booker is an experience full of contradictions. For any crewman who has spent years inside the cramped, deafening interior of an M1 Abrams, the Booker feels quite modern. The shared digital interfaces, crystal-clear FLIR thermal monitors, and familiar fire control hand grips make getting on target almost effortless. It handles like a dream in the mud, carving through tight turns and navigating wooded terrain where a main battle tank would instantly get bogged down
The reality inside the hatch is where the anxiety sets in. When you are sitting behind the controls of an Abrams, you know you are encased in depleted uranium composite armor designed to take a beating from the heaviest munitions on the planet and keep rolling. In the Booker, you are painfully aware of the thin steel and composite skin separating you from the outside world.
When you operate in close coordination with light infantry, you are naturally drawn into dense urban streets, choke points and tree lines. In modern warfare, those environments are absolute slaughterhouses, swarming with RPGs and cheap, deadly suicide drones. Operating a vehicle that looks and behaves like a tank, but cannot take a hit like a tank, demands a brand of hyper-vigilance that is mentally exhausting.
At the end of the day, the death of the M10 Booker is not the story of a catastrophic engineering failure. It is the classic story of development-creep running headfirst into the brutal reality of an evolving battlefield. It was a platform conceived during an era of counterinsurgency, designed to bridge a gap left behind by the Sheridan and the Stryker MGS, but finalized just in time to face a drone-saturated, near-peer operational environment that rendered its core concept obsolete.
You cannot fix an expeditionary mobility problem with a 40-ton vehicle, and you cannot survive modern multi-domain warfare with half-measures in armor. The Army’s decision to cancel the program before pouring tens of billions more into full-rate production may sting in the short term, but it stops the cycle of throwing good money after a flawed concept. The infantry’s dream of an organic, heavy direct-fire sledgehammer remains unfulfilled, but the lessons bought and paid for by the Booker will shape whatever machine takes its place on the firing line next.
When I Take my M1 Garand to the range. A lot of times there will be some guys who say how heavy they are and worry about the kick.
So I always share the story of how the inventor of the rifle John C. Garand used his children (pictured below). To demonstrate to the Military Brass on how easy the rifle was to operate and shoot. And as it went, the rifle was adopted into service and is a historical legend
Kentucky Woman Got Tired Of Waiting On Her Chicken, So Police Say She Pulled An AR-15 On A KFC Employee
A KFC incident making headlines across Kentucky reportedly began with an ordinary inconvenience before taking a dangerous turn. A Lexington woman is facing a felony charge after authorities said she pointed an AR-15-style rifle at a KFC employee during a confrontation over a delayed drive-through order.
According to WKYT, 33-year-old Nayda Roman allegedly became frustrated while waiting for food at the KFC on Richmond Road in Lexington. The reported confrontation happened on May 11, although Roman was not taken into custody until late July.
An arrest report states that Roman exchanged words with members of the restaurant staff before leaving her position in the drive-through line. Instead of leaving the property entirely, police said she drove around the building and entered the restaurant’s parking lot.
Authorities allege Roman then parked her vehicle, opened the trunk, and removed an AR-15-style rifle. The arrest citation claims she pointed the firearm at an employee in a “threatening manner.” Roman allegedly returned to her vehicle and drove away shortly afterward.
The employee was left to process a situation that allegedly escalated from a slow order to the presence of a high-powered weapon. While fast food customers regularly complain about long lines, incorrect orders and slow service, the allegations connected to this situation are far beyond a heated exchange at the window.
Investigators reportedly used multiple forms of evidence to identify Roman. Police reviewed security footage from the KFC and used the video to identify the vehicle involved in the incident. Officers then compared the footage with police body camera recordings from earlier traffic stops involving that vehicle.
Police also presented a photo lineup to the employee, who reportedly identified Roman as the person involved. The combination of the restaurant surveillance, previous body camera footage, and the employee’s identification ultimately led authorities to Roman.
Roman was taken into custody in late July and charged with one count of first-degree wanton endangerment. Jail records showed Roman was booked into the Fayette County Detention Center on Monday, July 27. LEX 18 reported that she was arrested on July 28, creating a one-day difference between the published timelines.
Under Kentucky law, first-degree wanton endangerment applies when someone allegedly displays extreme indifference to human life and creates a substantial danger of death or serious physical injury. The statute classifies the offense as a Class D felony. It becomes a Class C felony when a firearm is discharged during the offense. None of the reviewed reports allege that Roman fired the rifle.
The charge connected to the KFC rifle arrest remains an allegation and does not amount to a conviction. As of August 3, Law and Crime reported that Roman’s next court appearance had not been publicly confirmed. No plea, conviction, or final legal outcome was included in the latest available reporting.
Beyond the legal process, the case puts another spotlight on what restaurant workers may face while simply trying to complete a shift. Employees have no control over every delay happening inside a busy kitchen, yet the person working the window often becomes the most accessible target for a customer’s frustration.
No matter how Roman felt in the moment, the arrest now means navigating a felony case connected to what reportedly began as impatience over food. For the employee, it means being placed at the center of an encounter that allegedly became threatening without warning.
Bill Jordon applied his experience as a Marine in WWII and Korea and along the Southern Border with Mexico to help produce the concept that later became the S&W Model 19 (Photos: Richard Taylor/Guns.com)Designed with input from an early legend in the gun community, the Smith & Wesson Model 19 Combat Magnum has been a hit with wheel gun aficionados for generations.
To get the appeal of the Model 19, understand that S&W first debuted their medium-framed swing-out cylinder revolvers, known today as K-frames, back in the late 1890s with the Hand Ejector and Military & Police models.
Then came the larger N-frame hog legs in 1907 with the advent of the Triple Lock or New Century. While the “Ks” typically ran in .32 to .38 calibers, the “Ns” were offered in beefier chamberings like .44 Special and .44 Russian.
Fast forward to the 1930s and when the dream team of Elmer Keith, Phillip Sharpe, and D. B. Wesson joined forces to create the .357 Magnum cartridge, they developed an N-frame model to run it, the Model 27.
And so, it remained for decades until S&W heard from a WWII and Korean War-veteran Marine officer and U.S. Border Patrol supervisor, William “Bill” Jordan, about the what would make the perfect “combat” duty revolver.
In short, Jordon advocated a K-frame-sized double-action chambered .357. While today these seems as logical as peanut butter and jelly, it was revolutionary at the time and, after some R&D and trial and error, the K-framed Combat Magnum was created in 1955.
The standard Model 19 runs a 4-inch barrel with a ramp front sight and adjustable rear. Although chambered in .357 Magnum, they also accommodate .38 Special rounds as well. (Photo: Richard Taylor/Guns.com)
“Surely nothing could be more disconcerting to the accuracy of an adversary than a .357 Magnum slug applied judiciously in the region of his belt buckle! It will beat kicking dirt in his face every time!” said Jordan of the caliber in his 1965 book, No Second Place Winner.
Outfitted with a shrouded barrel with an enclosed ejector rod and an adjustable rear sight, the Combat Magnum that hit S&Ws catalog in the mid-1950s was built on a 4-screw frame with a square butt. The frame sported a larger yoke and a fluted cylinder that had been counterbored.
Unlike the Model 27 which was offered in numerous barrel lengths, the original Combat Magnum only came in a 4-inch format as standard. While a nickel finish was offered, most were in Smith’s bright blue finish of the time.

“In this country, we are fortunate that we have available to us the finest double-action weapons made in the world: The .357 Combat Magnum,” said Jordan, who later went into a second career as a writer and exhibition shooter. “Better guns cannot be bought at any price, anywhere. You can’t go wrong with one of these hanging by your side.”
By 1957, the Combat Magnum’s name switched to the Model 19 and the rest, as they say, is history.
As later generations of the Model 19 went into production, the general concept of the .357 K-frame endured with additional barrel lengths (2.2- and 6-inch) offered while round butt designs were added to the catalog.
The popular revolver was the gold standard across legions of lawmen of the age and was issued to both the Border Patrol and the FBI before those agencies ultimately shifted to semi-autos in the 1990s.
This led the medium-framed magnum to become a staple in small-town law enforcement, period bowling pin matches, and for use as a home and personal defense gun.
In turn, a myriad of fictional lawmen portrayed on screens both big and small carried the Model 19 including Danny Glover as Det. Roger Murtaugh in the Lethal Weapon franchise, Clint Eastwood (as both Texas Ranger Chief Red Garnett in A Perfect World and Agent Frank Horrigan in In the Line of Fire) and by numerous cops on Hill Street Blues.
Contrary to the he-man grips on the N-frames, the more medium-sized Model 19 K-frame guns allowed those with slightly smaller mitts to carry and use a .357, especially if the factory grips were changed (Photo: Richard Taylor?guns.com
By the early 1990s, the nickel offerings fell out of favor as Smith had previously introduced the satin stainless version of the Model 19 under the standalone Model 66 designation. For those wanting a more “budget” Model 19, the fixed-sight heavy barrel Model 13 M&P K-frame debuted in 1974.
Here we have several 19s on hand including some earlier 1960s-70s vintage 19-3 and 19-4 models as well as both blued and nickel finishes and specimens with 2.5-, 4-, and 6-inch barrels. (Photo: Richard Taylor/Guns.com)
Sadly, after a more than 40-year run, the Model 19 went out of production in 1999, a deficit that Smith corrected last year by bringing what could best be described as the 19-9 “Classic” back to their lineup.
Got to give the people what they want.
