U.S. Army Pfc. Kevin B. Mettler (front), 22, and Pvt. Jason R. Pompa (rear), 26, mortar gunners for Mortar Platoon, L Troop of the 4th Squadron, 2nd Stryker Cavalry Regiment based in Vilseck, Germany, cover their ears as a long-range training round is fired out of a 120 mm mortar which has a maximum range of 6,800 meters. The training rounds have cartridges similar to 12-gauge shotgun shells at the top of each round that detonates a white flash upon impact instead of sending out shrapnel as a live mortar would.
