2. Pretty good bait and switch, volunteer to be a tanker and then guard an airport for two years. Maybe they should help with the fall harvest too. Hey, they volunteered so we can make them do anything!
Your second point, well yes it may be disappointing to have signed up to ride around in a tank, but if your handed a rifle and told to guard this airport, thats what you do. I think its called following orders? After all, cooks and company clerks in WWII were handed rifles and told to fight when the situation called for it. I don't think any of them said, I just signed up to be a cook. That would have been something called insubordination, I think. Doesn't that lead to court martial?
