What are covers?
I had a military dad and my older brothers all did a stint, but I’m not well versed on military stuff...they were all AF.
From what I’ve read prior, and I’m not sure the reason, I didn’t think Marines were supposed to be in uniform in the civilian world. I definitely could be incorrect.
Cover = hat. While outdoors your head should be covered at all times.
Hat
They were in uniform, obviously coming from a USMC party. And yes, blues ARE authorized out in town, as are some other uniforms.
