The M449 projectile is an Anti-Personnel Improved Conventional Munition that is capable of delivering M43 anti-personnel grenades. During Operation DESERT STORM, the combined dud rate of multiple engagements with improved conventional munitions (such as APICM, DPICM, CBUs) cause obstacles and safety concerns for the maneuver commander. Some maneuver commanders hesitated to employ the munitions, especially if the unit might have to move through the area later.
