I fought in Afghanistan and Iraq, I know people who had been to all 4, and I really wish that you had not said that unless you are for real ready to strap a gun and stand guard at a post.
It's one thing to talk about war on an internet forum, watch it on TV or brag about it. It's another thing to actually gone down the dirty end and do the deed yourself. I have done things in war that you wouldn't even dream of doing to your worse enemy, and you wouldn't believe me if I told you. But war is like that, when it come to preserving your own life, you do whatever you do to stay alive.
Fighting a war is not a game, you don't get unlimited ammo, you don't use health pack to heal your amputation immediately, you don't get respawn when you died. Unless you are really, like REALLY ready to die for it, what you are saying is literally disrespecting people who had done their part in war.
