Yep, and our unit (1/635th AR/35 attached to 1st Div) had 7,000 body bags in our TO&E with Chemical officers attached at the company level since they were expecting a large number of CBRNE (called NBC back then) injuries from Saddam.
That was pretty scary. Did any evidence of actual NBC weapons ever turn up? I think Margaret Thatcher scared the crap out of the Iraqis when she assured them that Britain would nuke em if they used chemical weapons.
