The part where he shoots at them from a 2nd story building in training was filmed at School of Infantru at Camp Pendelton... We did our basic MOUT training there... (well all the MOUT training us non-grunts would get).... They call it MOUT Town.... but there is a gigantic area we saw as recruits nestled near "The Reaper" aka "Edson's Ridge" for our final "Crucible" hike.... that one was amazing... wish we could have done more MOUT in MCT...
