Abandon squad/section levels of organization?

[JMA]

There was a board game many (like 35) years ago called Firefight. It simulated combat in the ETO and the units went down to individual vehicles and groups of two men. It is interesting that in that game the most effective way to organize the infantry was exactly as you said, 1 MG per 4 man group.

I agree but with the caveat that not all MG are equal.
