A Soviet-built tank destroyed by an armor piercing round.
The tank in the picture above was destroyed by a cannon round that had no explosive charge. A solid shot hit the turret of this Soviet T-72 main battle tank and destroyed it, turning the approximately ten-ton-turret on its side.
The round that destroyed the 41-ton tank was a 25mm tungsten-carbide dart fired from a 120mm smooth-bore cannon in an American M1A1 main battle tank. The 25mm round is wrapped in 120mm casing that breaks away just past the end of the gun. Because the 25mm round is propelled with the force of a 120mm charge, the tungsten-carbide dart flies at more than a mile per second to its target.
The round makes a small hole when it it hits, but the mile-per-second impact can punch a hole in armor more than a foot thick at a mile or more of distance. The impact turns the armor on the inside of the tank into hot shrapnel that kills the crew and destroys the tank. At close ranges in can flip the turret over as in the photo above or even take the turret off a tank altogether.
When compared to firing explosive ammo at a tank, the solid-shot APDS (Armor-Piercing Discarding Sabot) round is also more accurate. The trajectory of an APDS round is so flat that point blank for a tank firing the round is one kilometer.
If cannon ammo was a football, the path of an APDS round is like a screen pass thrown by a strong quarterback--it flies flat and straight to the receiver. A high-explosive round flies like a 70-yard touchdown pass that rises steadily up for sixty yards before dropping into the receiver's arms.
I was a tank commander, before electronic computers became part of armored warfare. When my gunner fired at a tank or tank-sized target less than a kilometer away, he simply had to put his crosshairs on the target and fire.
