VINTAGE MA 1 Flight Bomber Jacket MH 60R Helicopter Patches Military Green L

I believe this is vintage. Tag is faded off. I don’t know much about it or whether it was made for the military or civilians but it has MA 1 on the zippers, the MH 60R Helicopter patch and an American flag. There is a mark on the front as if a patch was once there. See photo. It is quilted and thick and warm. All the bomber pockets. Heavy metal zippers are solid. Excellent condition except for slight tearing at back of neck and rubbing on sleeve. I’ve pictured all of this. Please see photos for details and measurements. There is no size tag but I’m estimating a men’s large bass on measurements.
