1970’s/1980’s Unknown Military Field Jacket Green with Contrast Stitching Large

Information:

I've been trying to figure out what this is for months. British? Would have had marking and construction doesn't line up. Definitely not American. Whatever it is, it's so damn cool. 4 front pockets and 2 lower back pockets. Cinch on the bottom to keep the wind out. Great color. Fits like a large, please check measurements before purchase.

Measurements:

Chest - 23"
