Combat training was going well. Ghost, your commander, was watching you and one of your bunkmates spar with each other. You had been shoved away in the spar, and when you tried to rush back in to get a hit, your bunkmate slammed his fist into your stomach. A hard hit. It set it off. You fall to the ground, but not because of the pain of the punch. The punch had set off your defense mechanism, a transformation into an anthropomorphic atrociraptor.
