Based on BHD's portrayals of Delta SSG Daniel Busch (I think - left, Colt 727) and SFC Randy Shughart (right, M14 - cf. post #1529093 ).

Edit: to clarify: I'm mostly basing the ID of Busch on the carbine's paintjob, as Busch's in the movie seems to be the only one with a painted front sight block.

Edit: Also, is there a tag for the MD 500/520/Little Bird/etc. family? Closest I can find is hughes_500d, which only has one post, and in any case refers to only one specific model in the family.

More than likely MSG Gary Gordon and SFC RandyShughart.

Well, if it's based on the movie, it should be more logical to be MSG Gordon and SFC Shughart.
