I suppose it depends on your personality. I've thought about getting a cap with an emblem, even shopped on E-bay. But, then I thought, would I really want to wear it in public? Would it be like saying, "Hey, I served in the military"? That's not me. But, if it makes some people happy to display their service, I'm fine with it. Maybe getting old and losing some of your abilities, it's a way of saying, "I used to be a tough guy". The last time I visited my cardiologist, there was a really old feeble guy in a wheelchair with a US Marines cap. I wouldn't deny him that. I bet he earned it.
The military was just a small part of my life. I'm proud that I served my time. But, I don't feel the need to advertise it.
