What interesting military bumper sticker or window decal have you seen?

I was driving on the highway when a truck briefly honked its horn. As he came up on my right, the driver saluted me and I saluted him back. I have a Marine Corps emblem on my license plate, and on his rear window, he had this decal:


Not So Mean

Not So Lean

Still a Marine


I thought this was a good decal and it also applied to me.
