False Advertising?

So after the fourth piece of literature based on war stories, and experiences, I think Uncle Sam needs to explain what the deal is. Apparently these soldiers don't expect half of what they experience before they sign their name away. After reading several pieces of literature based on past war experience, I feel my judgment on war has changed a tad. From what I hear all that pre-training in the U.S., of maintaining discipline at all times, and getting prosecuted for wrong doing, seems to be altered in times of "war". I mean I understand, through past wars in American history that the U.S. is "always right", which makes it that much easier to take over other countries, because we feel it's the "right" thing to do. However, I don't feel that the process should be made a mockery of. Listening to what these veterans have to say about what really goes on out there, past the papers, is a little disturbing.
