One of the things that many people did after they in processed and got their jungle issue boots and fatiques was to get a new hat. Any of the tailors located on or off base had them. It normally had on it your squadron,your tour dates, your name, where you were from, and maybe something across the top.

My hat showed that I was in MMS, was in Guam first and then Thailand, my name was Bill (the hash marks above the name are still visible - 1 for each month), I was from Balto. MD., and the last (for lack of imagination) was a popular expression among SAC (Strategic Air Command) troops.
