I am glad to see the photos of this training. When I was a chemical operations NCO in the US Army we rarely trained with more that personal NBC protective gear. Training with unit level equipment was mostly done at the chemical school. US soldiers don't like NBC defense training because the protective suits and masks are uncomfortable and they find the subject boring. Also, when I trained soldiers for Operation Desert Storm, they were not confident that they could survive a chemical attack. I wonder what is the attitude of IA in that regard. Certainly the threat should be recognized.
