Nice subject that really enhances and expands the existing set available. The anti-resistance troops came as a bit of a surprise, I was expecting Cossacks or Handschar, these look as though it is meant to be Gestapo and SS for Western Europe - not as much wargaming potential in my view.
If you add in some partisans as the enemy, some refurbished French tanks that were used in anti-partisan operations, I would say they are well suited for gaming.
Also, some of them can be used as actual partisans (like the coated figures), and some others could even be used as Poles in the Warsaw uprising.
Yes they have their uses but to me there were less stand up battles in the West because the terrain wasn't suitable to protect large scale formations, obviously, the Maquis were an exception but for a long time virtually all they could do was lie low and survive. Most of what happened in the West was raids and arrests of agents and small groups because they had been informed on or their radio transmissions had been detected. The Gestapo men are a bit different but supporting troops in this scale are pretty much indistinguishable from normal SS or Wehrmacht troops. Don't get me wrong, if you can make use of them then that is great but for me they don't have a great appeal.
