In the late 1990s one of the guys at work would appear to be slightly drunk or have some type of medical issue when walking. At some point he became part of the check crew and found out he was a Gulf War vet that, after leaving the service, worked as a civilian contractor doing ordnance cleanup in Kuwait and Iraq. He had a very large photo album showing the type of work and what was involved in the cleanup. Huge area impacted, HUGE cost to deal with it, and workers still got killed or injured cleaning the mess up.
It turned out he took the job where we worked for medical benefits due to issues he felt were a result of contact with expended military ordnance. Had a family with a new kid and he felt his medical prognosis was not good. Would hear from him off later as we moved on and things were not good. The article linked below sort of dovetails with mention and pics of extreme concentrations of certain munitions.
I'm no scientist so won't argue the after effects of any of that shit but fact is the leftovers from WW1, over a 100 years ago, are still a serious problem in Europe especially areas of France.
Also am not cheerleading on either side but have to say I don't agree with the level of U.S. involvement.
Anyway---here's one report, can't vouch that it is accurate or legit, but there are other similar reports if a person really wants to look for it.
