Past replacement efforts haven’t exactly been met with positive results. Here's What You Need to Know: The Bradley Fighting Vehicle remains a critical component in the U.S. Army. While the U.S. Army is continuing to seek a replacement for the Cold War Bradley Fighting Vehicle (BFV), the past efforts with the optionally manned fighting vehicle (OMFV) program haven’t exactly been met with positive results. In the meantime, the M2 Bradley—the fighting platform no one really wanted or really needed—continues to live on. The latest variant, the M2A4 has been undergoing testing at the facilities of the 3rd Cavalry Regiment of the 1st Cavalry Division of the U.S. Army at Fort Hood, Texas. The U.S. Army Operation Test Command has been conducting exercises with the upgraded Bradley, which features a new 8-cylinder Cummins VTA903E-T675 diesel engine with a capacity of 675 horsepower; and a new HMPT-800-3ECB hydraulic transmission. These improvements will allow the fighting vehicle to utilize the Iron Fist Light Decoupled (IFLD) active protection system for armored vehicles developed by the Israeli Elbit Systems company, Defence-Blog reported.
