Army's Armored Multi-Purpose Vehicle (AMPV): Background and Issues for Congress [May 31, 2017] [open pdf - 576KB]
"The Armored Multi-Purpose Vehicle (AMPV) is the Army's proposed replacement for the Vietnam-era M-113 personnel carriers, which are still in service in a variety of support capacities in Armored Brigade Combat Teams (ABCTs). While M-113s no longer serve as infantry fighting vehicles, five variants of the M-113 are used as command and control vehicles, general purpose vehicles, mortar carriers, and medical treatment and evacuation vehicles. The AMPV is intended to be a non-developmental program (candidate vehicles will be either existing vehicles or modified existing vehicles--not vehicles that are specially designed and not currently in service). Some suggest a non-developmental vehicle might make it easier for the Army to eventually field this system to the force, as most of the Army's past developmental programs, such as the Ground Combat Vehicle (GCV), the Future Combat System (FCS), the Crusader self-propelled artillery system, and the Comanche helicopter, were cancelled before they could be fully developed and fielded [...] The FY2018 budget request for the AMPV requests $647.4 million for the production of 107 vehicles. A potential issue for Congress is whether the Administration's proposal to increase the size of the Army will translate into a requirement for additional AMPVs."
