Armament M802A2 60 mm mortar smoke bomb. Development By US Army Ordnance. Description The M936 is an impact, super-quick (SQ) and delay fuze for use in the M802A2 60 mm mortar smoke bomb fired from M2, M19 and M224 mortars. Safety is via a pull pin and arming pin which lock the arming slider. The arming pin is restrained by the M53 pyrotechnic delay and the pull pin. The fuze is set before firing by rotating a slotted shaft in the fuze body and removing the pull pin. Upon firing, setback forces move a plunger pin
rearward against its spring, freeing a ball detent and the firing pin. The firing pin moves forward after acceleration under spring pressure and partially frees the slider. Acceleration also moves a second plunger to the rear, releasing a second ball that frees a delay arming firing pin. Acceleration moves this pin rearward, firing the M53 delay. After the 2 to 6 second delay has burned, it removes the arming pin from the slider that arms the SQ or delay alignment. On impact, the fuze firing pin fires the M98 SQ or M76 delay detonator, which initiates the lead and booster. Manufacturer US government contractors.
