Our military style of warfare has part to blame for this as Sledge has said. 3 or 4 tours? That is the norm now, but I believe mentally, that's got to be enough to drive a man insane. Not just from all the killing, and fear of always being killed, but the fact that his wife never sees him, and who knows, he could of found out she is cheating on him, because he is not there, or she broke up with him, and at this point, if he had seen a lot f combat, PTSD's is almost certain.
If our military style of warfare wasn't to be the police of the world, staying in countries, not winning wars, but occupying them for 10 years or more, and not meeting any sense of a military battle plan of winning, just staying, occupying, and running the PC wars, have a huge impact on this.
We used to bring everything we had, kick ass, take names, kill everybody, and then get out, that's the way we used to do war, and its the way we should do it now, compared to the BS that we put our troops through now.
We need to go back to this, or we're going to see a whole lot more of these soldiers losing their minds and doing horrible stuff. Its just going to happen, its not humanly normal to do things like this forever.
I know this is war, its ugly, and its supposed to be, and things like this are just going to happen, but you can't help but think that some of this is to blame on the way that we fight wars now, and the fact that it needs to change.
Also, another off-topic note, when my grandfather got done with his duty in WWII, D-day +1 all the way through until we toppled Berliin, after he got done fighting, the military sent him around the world for ONE YEAR, before he ever saw his wife and kids again.
Now they just give you a plane ticket, and you are literally killing people one day, and the next day you're hugging and kissing your wife. I think that shit needs to change too. You know that is bound to cause problems as well. They have no time to decompress from the stresses of killing people, taking fire, seeing your buddy get shot or blown up, and then coming home the next day or week, and seeing your wife, kids, and hugging them and stuff. That's just not right. Every human needs time to decompress after killing, taking fire, seeing buddies blow up, die, get shot, and being back here in the civilian world. To me, its asking for problems.
Why not just go back to the old way of conducting war and troops? Seemed to work a lot better back then, and we probably had a less number of problems. You will never completely get rid of all problems mind you. I don't think that is possible at all. War is nasty, ugly, and it can make even the most normal man crazy.
