wtf is that !?

In a military barracks, a drill instructor in a tan uniform bends over to pick up a piece of bread from a box while recruits in white uniforms stand at attention, and the instructor exclaims "¡Santo Dios!" followed by "¿Qué es esto?" and "¿Qué coño es esto?" before standing up and holding the bread. The scene cuts to a close-up of a man with dark hair speaking.
