The assessment of these options is being undertaken by an integrated product team comprising representatives from the Infantry Center; the Armament, Research, Development, and Engineering Center; the Program Executive Office Soldier; and each of the other armed services. Individual Carbine Competition

The Army intends to conduct an open competition for a successor to the M4. Its proposal is before the Joint Requirements Oversight Council for approval and, if approved as expected, would permit the Army to solicit submissions from the small arms industry by this fall. Complete results of the competition and selection of a new carbine are not expected before FY2013, and it is anticipated that it would then take another three to four years to fully field the new weapons. Concerns with M-4 Reliability and Lethality

Reports suggest that soldiers have expressed concerns regarding the reliability and lethality of the M-4. Other reports, however, suggest that the M-4 has performed well and been generally well-received by troops.
The M-4 carbine is the Army's primary individual combat weapon for infantry units. While there have been concerns raised by some about the M-4's reliability and lethality, some studies suggest that the M-4 is performing well and is viewed favorably by users. The Army is undertaking both the M4 Carbine Improvement Program and the Individual Carbine Competition, the former to identify ways to improve the current weapon, and the latter to conduct an open competition among small arms manufacturers for a follow-on weapon. An integrated product team comprising representatives from the Infantry Center; the Armament, Research, Development, and Engineering Center; the Program Executive Office Soldier; and each of the armed services will assess proposed improvements to the M4. The proposal for the industry-wide competition is currently before the Joint Requirements Oversight Council, and with the anticipated approval, solicitation for industry submissions could begin this fall. It is expected, however, that a selection for a follow-on weapon will not occur before FY2013, and that fielding of a new weapon would take an additional three to four years.
