During the fighting on Iwo Jima in 1945, a mortar squad engages in a fire mission. The gunner (at right) checks his sight to make sure it is aligned. The assistant gunner (at left) hangs an M57 smoke round in the tube. In the background, a stack of HE and smoke rounds is ready to fire. Sometimes, mortar platoons fired hundreds, or even thousands of rounds each day in combat. Still image from USMC combat camera film.
