The Army’s Biggest and Baddest Troop Carrier Might Get Even Bigger

The M2 Bradley infantry fighting vehicle is nominally used to carry infantry into battle, but is frequently misidentified by journalists as a tank. This is understandable, as the tracked vehicle currently tips the scales at thirty-three tons from all the add-on armor it has received, and bristles with both a twenty-five-millimeter Bushmaster automatic cannon and a TOW antitank missile launcher.

Oddly, critics of the vehicle have sometimes complained that the Bradley’s sheer firepower often makes the infantrymen it carries onboard an afterthought. In theory, the onboard mechanized infantry squads are supposed to dismount in denser terrain to scout out enemy positions and ambushers, maintain defensive perimeters, and flush adversaries out of buildings and other built-up areas that the Bradley can’t reach.

However, a notable limitation of the M2 as a troop transport is that it can carry just seven dismounts—in earlier models, just six—while a mechanized infantry squad currently has nine men. Each mechanized infantry platoon therefore has to divide three squads between four Bradleys, meaning that all the members of squad are not able to ride in the same vehicle.

The Army is halfway through a two-stage update process for its roughly 1,800 remaining M2 and M3 Bradleys, to restore automotive power to the chassis and upgrade its computer systems to be more accommodating of to future improvements. In January 2018, it emerged that an even more ambitious M2A5 upgrade is being planned for the mid-2020s, which might stretch out the hull to carry more armor and personnel and install a more powerful thirty-millimeter cannon turret.

That’s right: the Army’s biggest and baddest troop carrier might get even bigger.

The M2A4 Automotive Tune-Up

The U.S. Army’s Bradleys have likely seen even more use in combat than the more famous M1 Abrams main battle tank. In swirling mechanized battles in the open deserts of Iraq in the 1990–91 Gulf War, the Bradley reputedly destroyed even more armored vehicles than Abrams.

Only three Bradleys were destroyed by enemy fire in that conflict, though considerably more were lost to friendly fire. However, more than a decade later, the Bradley suffered dozens of losses in the United States’ prolonged counterinsurgency campaign in Iraq, despite efforts to bulk out the vehicle’s protection with bricks of explosive reactive armor and additional armor plates. The Bradley was simply not designed with protection from mines and improvised explosive devices (IEDs) as a priority, and sometimes sustained more damage from them than more lightly armored Stryker wheeled APCs.

While measures to beef up the armor and improve sensors have been partially effective, the extra weight has taxed the vehicle’s engine and electrical systems to the limit and degraded mobility. Starting in 2012, the Bradley began undergoing an upgrade to a new M2A4 standard, which is being implemented in two “Engineering Change Proposals.”

ECP1 is nearly complete, and involves restoring the Bradley to its original automotive performance by installing heavyweight torsion bars and track upgrades, improved suspension and new shock absorbers. This will reduce wear, improve reliability and raise the ground clearance—which would also improve survivability versus IEDs.

The second ECP is intended to revamp the vehicle’s electrical systems and power train to accommodate higher power-consumption demands imposed by new vehicle systems and install smart power-management software. Originally slated to begin in 2018, a new report explains that there have been delays to EP2 due to reliability problems and software bugs; the upgraded Bradleys are experiencing system breakdowns every 281 miles on average, instead of the desired four hundred, due to power-pack failures and problems with the transmission oil cooler. Nonetheless, implementation of EP2 is expected to begin soon, especially after new software comes out in February.

The Bradley upgrades also pertain to the very similar M3 Cavalry Fighting Vehicle, which is used by armored reconnaissance units, and the M7 FIST artillery direction vehicle. Once complete, they M2A4 model will exhibit higher performance and be ready to take on even more weight for a more ambitious upgrade to a conceptual M2A5 model.
