Munitions - APFSDS (KE)
APFSDS stands for Armor Peircing Fin-Stabilized Discarding Sabot, and refers to a long, thin Kinetic Energy (KE) penetrating rod (usually tungsten or depleted uranium (DU)) which uses a plastic or metal "shoe" (sabot) to fit snugly inside the bore of a large-diameter gun.  After having been fired, the sabot falls off, leaving only the dart-like penetrator to fly through the air and strike its target at very high velocity.  It is stabilized en route by the fins on its back end.  APFSDS is considered the best tank-killing munition on the field today, when fired from a high-pressure, large-bore main gun.
