I was watching the Unit the other day, and the episode was about a Chlorine strike, sorry if you haven't watched it yet. It made me think, that these "soldiers" were trained to recognize the type of attack, which allowed them to respond. Does anyone know of any good resources that describe what to look for, how to respond, and how to treat various related ailments. I have been in NYC during the blackout and 9/11, and it reminded me about the threats NYC faces. Thanks in advance.
