Just Banging Away with a 120mm Tank Gun (VIDEO + PHOTOS)

By Chris Eger

Army, Marine, Reserve, and National Guard tankers regularly get to head to the range to stay proficient with the big 120 mm tank gun, which packs a wallop.
The German-designed gun (they learned a few things about tanks over the years) originated with Rheinmetall in the 1970s and equips most M1 Abrams main battle tanks as well as the German-made Leopard 2. Smoothbore, the nearly 18-foot long gun has a 4,000m range and can fire everything from tank-eating sabot rounds to the M1028 Canister round, the latter filled with hundreds of tungsten balls that effectively turn a tank into a 73-ton mobile shotgun.

The shells fired by the 120mm gun weigh between 40 and 50 pounds depending on type. The Soldier here is holding an APFSDS sabot round, identified as practice ammunition by its distinctive NATO-designated Saxe-Cobourg blue color. (Photo: 1st Lt. Robert Barney/U.S. Army)
