I not really a skirmish gamer. Tactical, yes (platoon and up) but not a single section, although I have dabbled.
At the moment we use Fistful of Lead for WW2 skirmish, and that seems to work OK, although we tend to run platoon sized scenarios LOL.
I guess my favourite game at this scale was AHGCs Up Front, which captured the essence of small unit fire and movement very neatly.
From a gaming pov, my biggest issue with skirmish is plausible scenarios. There is very little a WW2 rifle section can do on its own apart from patrol. The Skirmish Campaigns scenarios are great, but pitched at rather bigger battles.
