I don't know about increasing risks of suicide, but I can't help but believe that being involved in combat, especially close combat, where you can see your opponent, has to have some kind of effects on people's minds. War drives soldiers to perform acts which are considered wrong in any civilized society, yet those acts must be performed to perpetuate that society. It's frightening to see how many of our military people come back with severe psychological and emotional scars.

What's even more frightening, though, is how little the government which sent them there is willing to do to help heal them. More must be done to insure that those who would send troops into combat, politicians and those running the industries, are first of all intimately familiar with what they are asking those soldiers to do, and secondly are forced to help heal those soldiers when they return.
