APDS: Armour Piercing Discarding Sabot, This shell has a sabot formed around the penetrator that drops off when fired from the gun. The smaller penetrator itself then adds the Kinetic Energy from the sabot to it's own speed and increases the speed at which the penetrator flies and strikes the target. The higher speed coupled with a small dense penetrator results in increased penetration.
APFSDS: Armor Piercing, Fin Stabilized, Discarding Sabot; a type of anti-tank rounds that defeat an armored target by means of kinetic energy of a subcaliber projectile placed inside of a sheath, or 'sabot', that is discarded in flight. Russian APFSDS rounds have a designation 3BM[number]
