Good luck to the Colonel on his hospitalization/surgery. My bad on the chem weapons..was off by a few years.
Agree 100% that chem weapons more "hassle" than dangerous for well trained troops - I've been in full gear in the heat, and done triage/simulated casualty treatment and decon. Uncomfortable & tiring & reduces efficiency. with chem weapons, best thing to do is get out of the area if you can - and a lot depends on the type of agent (nerve vs blister vs choking vs blood), its persistence and the temperature and weather (rain helps clean things up, heat degrades etc). WP gas gear was way less user friendly than NATO - troops would rapidly overheat/dehydrate.
One thing huskers can be doing is seeing how many greenhouses folks can build for themselves - this allows for growing of things like vegetables, even some fruits that will provide both nutrition and vitamins and also be protected from fallout. Certainly every existing greenhouse - commercial, small florists, private, should be planting food crops right now not flowers.
