Well, since we are now talking "training-related" knowledge:
1. Don't ever try and figure out the Air Force. Just leave them be.
2. In the Navy, 0800 means 0815, not 0745.
3. The Navy civilian workday begins around 8-ish and ends precisely at 1529.
4. The phrase "Training Time Out" sounds silly.
5. Navy training commands actually provide commuting students with parking spots. What a concept.
6. PT can actually consist of fun sports (volleyball), not just mindless formation runs. (Well, I knew that from back in the *ahem* "Old Corps," but being in training commands for the past few years caused me to forget it.)
7. Classroom etiquitte - What is that again?
8. As a butterbar, never refer to an O-3 as "Sir" or "Ma'am." It is always "Hey L-T," or "Yo, Cap'n."
9. 11-year squids with wives and kids, trying to keep their NSS in the pilot range, make great study partners.
10. Yes, Virginia, you can stuff 55 officers into a room designed for 15.
