I agree with a sweater. The USMC currently has an OD green pullover with epaulets, that would look great with our current Khaki, OD uniforms. I have seen similar versions referred to as a commando sweater. I was a cop in a past life, and we wore a navy blue version of the same, I rarely needed or wore a coat when I had the sweater on. Oh and by the way, I like berets too, hahahaha.
