The K419-1(M) grenade consists of a Visible/IR smoke payload and a Millimeter Wave smoke payload. Characteristics The grenades are loaded into the launching device. The electrical system is initiated to activate the electric match and ignites. Pressure build up in the base of the grenade body and the grenade is ejected
