Defense Technology Direct Impact and Exact Impact 40 mm impact munitions are point-of-aim, point-of-impact direct-fire rounds with a maximum effective range of up to 120 feet. These impact munitions consist of a plastic body and a crushable foam nose that can also contain a powder payload. This payload area can hold inert, marking, OC, or CS powder. The crushable foam nose dissipates energy upon impact while releasing the powder payload. Both munitions are available in an extended range LE version, which provides a maximum effective range of up to 230 feet.
