The M433 is a 40mm low-velocity High-Explosive Dual-Purpose (HEDP) projectile used in under-barrel and standalone grenade launchers such as the M203 and M320. It was developed to give infantry a compact round that can both produce fragmentation effects against personnel and a shaped-charge effect against light armor.
