Army's Optionally Manned Fighting Vehicle (OMFV) Program: Background and Issues for Congress [Updated June 8, 2021] [open pdf - 1MB]
From the Document: "The Army's Optionally Manned Fighting Vehicle (OMFV) is the Army's third attempt to replace the M-2 Bradley Infantry Fighting Vehicle (IFV) which has been in service since the early 1980s. Despite numerous upgrades since its introduction, the Army contends the M-2 is near the end of its useful life and can no longer accommodate the types of upgrades needed for it to be effective on the modern battlefield. Because the OMFV would be an important weapon system in the Army's Armored Brigade Combat Teams (ABCTs), Congress may be concerned with how the OMFV would impact the effectiveness of ground forces over the full spectrum of military operations. Moreover, Congress might also be concerned with how much more capable the OMFV is projected to be over the M-2 Bradley to ensure that it is not just a costly marginal improvement over the current system. A number of past unsuccessful Army acquisition programs have served to heighten congressional oversight of Army programs, and the OMFV may be subject to a high degree of congressional interest."
