Rules we all think are true, but not written anywhere?

With the Marines: "Black Flag PT restrictions only apply if you can actually see the flag."

Also: "High and Tight haircuts are only for enlisted members - not officers."

And has anyone mentioned: "Officers don't get/have tattoos."

One I think ought to be written down (as I always had to remind myself): '"You're never as funny or as clever as your juniors/subordinates make you feel."

I agree with Tsgt Koenig, there is that unwritten rule that many awards and decorations officers and commanders love to enforce. Professionally, the award of medals must be equal to the standard of the achievement by the person receiving the award. This unwritten rule of "you're awarded the medal/commendation according to your rank is a load of crap. Just because you're an E4/E5, doesn't mean you're not eligIble for the MSM or higher. But many a E9 or O4 would argue the point. Because they're jealous of your achievements.

...tradition??
