First Combat:   During Tuppers first mission he realized that it was a lot different then he thought it would be.  I learned about a thing called "shoot and scoot" that is a type of combat that means shooting while driving.  His first mission he got a radio call from the Taliban, and so they got prepared by driving the Humvee and motorcycles (mostly went to hot rural areas). A few chapters later he talks about how he almost died while in combat and how he had to give one of his fellow partners first aid, and how difficult it was to do.
