U.S LMG Team supermen?

[Smersh]

I've come across this american unit in a late 80s battle. at first I thought I was facing a much larger unit, all the smoke and crater made it difficult to see that it was only 2 men! there is one problem however. their weapons: a SAW, M16, LAW, and gernades.

how can a 2 man team shoot all these weapons, unless their supermen!
