That's essentially how the Army treats it as well, but I've not heard of situations where individual fireteams were deployed, except on more specialist actions like reconaissance patrols and the like.

I guess the designs felt that by allowing people to deploy individual fireteams, and how this is not really inaccurate, that it would give a greater degree of flexability to play with. I had originally thought that were the same size as normal infantry units and went back and looked and they were not. It also gives the USMC OOB a sort of "Cav Scout" size unit too, where it might otherwise be without one.
