Ok, Here's some visual reference.
This is my section at C&D canal in 2001. That's me second from the left, wearing an M-1942 jump jacket. To the left of me is my section SSGT, wearing an M-41 field jacket and to the right is one of his team leaders, wearing an M-43 field jacket. The remainder of the section is wearing a mix of M-41 and M-41 Arctic jackets. Trousers are either M-1942 Mountain trousers (very similar to jump pants in some respects) or M-1943 field pants (what the airborne troops modified in August of 1944 by adding cargo pockets).
They are all wearing M-2 jump helmets (except me, of course, but I'm a $@$^! officer
) You can clearly see the tan shade for the jump jacket here and the definite green of the M-43 field jacket.
I've got plenty of photos, so please feel free to email me!
