The TV networks have been showing quite a bit about the military hospitals and the post-war care or lack thereof for veterans. Post traumatic stress is showing up in many of the Iraq veterans, for good reason, considering the randomness of the roadside bombs. Many of the soldiers who were not directly injured by a bomb have been shown to have head injuries from the concussive force of the bomb blasts.
And there are others who have been killed or injured in Iraq. The military hires many civilian contractors to provide basic services, reconstruction skills, as well as security services in Iraq. When these "veterans" come home, if they do, since 900 have been killed, they don't get the life long medical benefits that the "real" veterans get.
