Military coat with removable liner zip up army green distressed 1989 Large Fall

Vintage military coat with removable liner. Zip up with button overlay. Pockets. Army green. I included measurements in pictures. No size tags in the coat. My son who is 6’4 180 is wearing it and you can clearly see it zips but is short on him in the arms so I am judging it to be a medium/ large. Can attempt more measurements for serious inquiries. Tag says 1989. This is a heavy warm coat when worn with the liner . There are no holes in the coat or pockets, distressed naturally due to age, tiny paint speckles on the back barely noticeable .
