I was under the impression war was something like a Wolfenstein 3d, but according to this new documentary featuring interviews with soldiers back from the war, The Ground Truth, it's not all switching weapons and killing Nazis. It's apparently a fairly traumatic experience to be trained to kill and sent to a foreign country, where you must witness and cause the deaths of an untold number of people. The switching weapons part is still probably pretty cool, though.
