I was a marine more than forty years ago and have been in combat many times and still remember what I learned about fire and movement ( shoot and scoot) and how to use cover and never run in straight line always zig zag, but I wouldn't want to be a war photographer I was in combat because I had no choice and at least I was armed and trained to be able to defend myself, war photographers are not allowed to be armed because as none combatants it breaches the Geneva Convention and they are in a war situation by choice. War photography is an even more dangerous profession than soldiering because you are a "soft target" for any enemy fighter with a weapon so this training school in the above link is a very good thing for photographers who want to do it for real, but I personally wouldn't want to put my family and friends through the stress, and anxiety of worrying about me because I still sometimes have flashbacks in daytime and nightmares even after all this time, I wouldn't want to put myself in a battle situation again and I'm now too old
