As Never anonymous Bud stated so eloquently:

I don't remember anything about an explosion, so probably before.

I fired Expert on the M16 twice while there.

I know they expanded the hospital not long after I left.

I believe it was in 1972 or maybe it was building 1972.

I got to fire a few different weapons while I was there.

It was a really nice hospital when I was there, comparable to the money
making hospitals in civi life.
