NSW type modifications, same velcro and pocket arrangement as Sample 10.  Found together with Sample 10.  Appears to be totally unused.

Sample 12:

Arm pockets stitched by hand in the field.

Sample 13:

Ranger style velcro arrangement.  This modification was done at the factory since the item is new (still has hang tag) and stitching for velcro is not visible from the outside.  Handwritten NSN 8415-01-162-6766 (assigned October 25, 1980) predates the printed 8415-01-390-8544 one (assigned May 27, 1994) that was crossed out.

 

Sample 14:

    

Standard twill woodland BDU, except with strobe pouch attached to left arm.  Circular patch ghost on left upper pocket.  Likely associated with Navy, maybe Naval Special Warfare, since it was found at a swap meet with other Navy BDU’s with varying name tapes.

Similar BDU with ABA vest over it from AFSOC training? (source: https://www.facebook.com/photo.php?fbid=2622428464435006&set=g.1587170878211879):
