More history, warts and all
Chemical warfare has been around for a long time. In WWI it was especially horrific, as they discovered it could be just as dangerous for the people using it as for the enemy. Here's Uncle Henry modeling the 1917 version of the MOPP suit:
As a Master Sergeant Uncle Henry trained troops on the newfangled Lewis machine guns. Due to the racial segregation in place at the time, he wasn't allowed to train the black soldiers -- he trained their officers, who then went back and trained the enlisted. When he was telling me about this his voice had a "would you believe it?" tone. He was a remarkably open-minded man for his time, and didn't see how skin color affected a guy's ability to operate machinery.
