You definitely got me beat for OJT. We were in the ‘same’ WWII temp barracks in 73. I believe they were finally torn down in the 1980s.
Did they ask anyone if they wanted to be “firemen”?
Some volunteered only to discover a fireman is the guy that shoveled coal in the furnace. We also had “firewatch”. Because the buildings were so old there was a risk of fire so someone had to be awake during the night. Two hours on four off.
When ever I smell coal burning I immediately think of Fort Knox.
