Visible crew/equipment: Near the ending when Braddock and the kids are about to escape and Braddock is killing off the rest soldiers in the camp, an explosion goes off by him which causes him to fly into the air and get injured. When he flies in the air, if you look at his feet you will see a chute/trampoline that launches him in the air.
Littlejohn: Braddock! I'm warning you, don't step on any toes.
Col. James Braddock: I don't step on toes, Littlejohn, I step on necks.
