Sgt. Michael Cucinotta, a combat instructor with the Advanced Machine Gunner Course, Advanced Infantry Battalion-East, supervises a student shooting an Mk-19 mounted on a Humvee during AMCG, aboard Camp Lejeune, N.C., April 30, 2015. Marines shot the Mk-19 from the mounted position and the unique defilade position. After two days of classroom work, the students received practical application of the defilade shoot which no other AMCG receives. Marines shooting from the defilade are firing on a target with an obstacle between them, protecting them from enemy fire, similar to firing a mortar. (U.S. Marine Corps photo by Cpl.
