I was listening to some veterans stories who were deployed on ships during the first gulf war1990/91. They said when they were ordered to take the Pyridostigmine bromide tablets. They also took the anti malaria pills. The area was infested with mosquitoes so army and sailors were also told to use DEET. Looking at this from the outside I have to say anyone taking these tablets plus putting deet on your skin will definitely get sick possibly for he rest of their lives. Then near the end of he conflict many of these folks were exposed to a cloud mixture of smoke and petroleum by-product from the burning oil fields of Kuwait. The ship was tasked to sail thru an oil slick and smoke in order to reach a disabled American ship (USS Princeton) just off he coast of Kuwait. Folks who spent the most time on the upper decks got sick the most. Nobody should have been allowed to stay on the upper decks in these conditions. All people exposed should have been given proper compensation.
