Considered a reliable and versatile vehicle, a number of different variations of the M-113 were produced to fulfill such roles as a command and control vehicle, mortar carrier, and armored ambulance, to name but a few. The 114 M-113 variants in the ABCT are distributed as follows:

	AMPVs at Echelons Above Brigade (EAB)5

In addition to the AMPV requirement in the ABCTs, the Army also planned to procure an additional 1,922 AMPVs to replace M-113s in Echelons Above Brigade (EAB). DOD estimates if the M-113s are replaced by AMPVs at EAB, total program costs could be increased by an additional $6.5 billion. The Army completed the AMPV analysis of alternatives (AoA) in July 2012 and proposed a nondevelopmental vehicle (the candidate vehicle will be either an existing vehicle or a modified existing vehicle—not a vehicle that is specially designed and not in current service). Department of Defense (DOD) Approves AMPV Program10

On November 26, 2013, DOD issued an Acquisition Decision Memorandum (ADM) officially approving the Army's entry into the Milestone B, Engineering and Manufacturing Development (EMD) Phase. This RFP stipulated the Army planned to award a five-year EMD contract in May 2014 worth $458 million to a single contractor for 29 prototypes. While the March 2013 RFP established an Average Unit Manufacturing Cost Ceiling for each AMPV at $1.8 million, this was rescinded to permit vendors greater flexibility. The EMD phase was scheduled to run between FY2015 and FY2019, followed by three years of low-rate initial production (LRIP) starting in 2020. Selected Program Activities

		Army Awards ABCT AMPV Contract to BAE12

On December 23, 2014, the Army announced it had selected BAE Systems Land and Armaments L.P. as the winner of the EMD contract. The initial award was for 52 months valued at about $382 million. In addition, the award provided for an optional low-rate initial production (LRIP) phase award in the future. AMPV Completes Critical Design Review

According to reports, the AMPV successfully completed its Critical Design Review (CDR) on June 23, 2016. Roll Out of First AMPV for Testing15

On December 15, 2016, BAE delivered the first general purpose AMPV to the Army for testing. AMPV Begins Developmental Testing17

In September 2017, the Army reportedly started reliability, availability, and maintainability (RAM) testing for the AMPV. The Army had planned to issue a request for proposal (RFP) for upgraded M-113s in the summer of 2018. Given the aforementioned 2017 DOD IG concerns and GAO's 2018 concerns regarding cost growth, difficulties meeting a variety of developmental requirements, and dependencies on other programs that are experiencing developmental challenges, the AMPV program will likely receive significant scrutiny and oversight to insure it remains a cost effective and viable program. Potential Issues for Congress

		The Way Ahead: Upgraded M-113s at Echelons Above Brigade (EAB)

As previously noted, the Army's optimal solution would be to replace EAB M-113s with AMPVs, but the Army felt that given current and projected budgetary constraints, only selected EAB units outside the continental United States and in South Korea and Europe would receive AMPVs while the remainder would receive upgraded M-113s as an interim solution. Reportedly in January 2019, the Army decided to cancel M-113 at EAB replacement efforts. DOD Inspector General (IG), Government Accountability Office (GAO), and Director, Operational Test and Evaluation (DOT&E) Concerns

DOD's April 2017 IG report, while acknowledging effective management of the AMPV program, also raised fundamental concerns about performance and design, as well as inaccurate procurement quantities, which could adversely impact program costs. Potential Revised AMPV Procurement Rate

As previously noted, on March 13, 2019, Army leadership reportedly announced the Army had decided to cut funding over the next five years for 93 programs—including the AMPV—to increase available funding for its new modernization strategy. While the Army is not expected to change its overall AMPV top-line requirement, it could slow the per- year procurement rate.
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 nondevelopmental 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 nondevelopmental 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.
On November 26, 2013, the Army issued a Request for Proposal (RFP) for the AMPV. This RFP stipulated the Army planned to award a five-year Engineering and Manufacturing Development (EMD) contract in May 2014 worth $458 million to a single contractor for 29 prototypes. While the March 2013 RFP established an Average Unit Manufacturing Cost Ceiling for each AMPV at $1.8 million, this was rescinded to permit vendors greater flexibility. The EMD phase was scheduled to run between FY2015 and FY2019, followed by three years of low-rate initial production (LRIP) starting in 2020. As of 2018, the Army planned to procure 2,936 AMPVs to replace M-113s in ABCTs. The Army also has plans to replace 1,922 M-113s at Echelons Above Brigade (EAB), and the Department of Defense (DOD) estimates that if the M-113s are replaced by AMPVs at EAB, total program costs could be increased by an additional $6.5 billion. While the Army would like a pure fleet of AMPVs, budgetary constraints could preclude this.
On December 23, 2014, the Army announced it had selected BAE Systems Land and Armaments L.P. as the winner of the EMD contract. The initial award was for 52 months, valued at about $382 million. In addition, the award provided for an optional low-rate initial production (LRIP) phase. The EMD contract did not include EAB AMPV variants. The AMPV reportedly successfully completed its Critical Design Review (CDR) on June 23, 2016. On December 15, 2016, BAE delivered the first general purpose AMPV to the Army for testing. In September 2017, the Army began AMPV reliability, availability, and maintainability (RAM) testing. Also in 2017, based on budgetary constraints, the Army decided it would upgrade a number of EAB M-113s instead of replacing them with AMPVs. In May 2018, the Army decided to put the EAB M-113 upgrade effort on hold. On March 13, 2019, Army leadership reportedly announced the Army had decided to cut funding over the next five years for 93 programs—including the AMPV—to increase available funding for its new modernization strategy. This cut is not expected to affect the overall AMPV requirement but could slow the AMPV production rate.
Other program issues include DOD Inspector General (IG) concerns regarding performance and design concerns, as well as inaccurate procurement quantities, which could result in inaccurate program costs. The Government Accountability Office (GAO) in 2018 expressed concerns regarding cost growth, difficulties meeting a variety of developmental requirements, and dependencies on other programs that are experiencing developmental challenges.
Potential issues for Congress include a "way ahead" for upgraded M-113s at EAB, DOD Inspector General (IG) and GAO concerns, and the potential revised AMPV procurement rate.
