[FMA] Skirmish

I'm just wondering here what people consider a skirmish game, and how
they
see FMA developing (assuming they know about it) or what they expect
from it
(if they don't)

Here's my yardstick:
Dirtside	  Company To Brigade Level
Stargrunt	  Platoon to Company
FMA Skirmish	  Squad to Platoon
FMA RPG 	  Single to Squad

What level of detail should each trooper be characterised ?
Here I assume that FMA would cover anything from Platoon level down to a
single character,  and that the weaponry involved Should be expanded to
show
a difference between weapons in the same general category.

Any thoughts ?
