Anti-tank

Anti-tank grenades are specialized hand-thrown grenades used to defeat armored targets, usually with a HEAT (internal cone) design. High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The grenade functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity explosively formed penetrator (EFP) jet. This is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge. Although their inherently short range limits the usefulness of hand grenades, troops can lie in ambush or maneuver under cover to exploit the limited outward visibility of the crew in a target vehicle. Thus some countries still use anti-tank grenades they have become redundant with the introduction of standoff rocket propelled grenades.
