This is just a quick question, but does anyone know what all the impact effects relate to? I have my guesses, but I wanted to see if anyone knows before I go and test them. My guesses are as follows:

ImpactEffectSoft= Troops/Animals?
ImpactEffectRigid= Vehicles?
ImpactEffectStatic= Props/Buildings?
ImpactEffectTerrain= Terrain
ImpactEffectWater= Water
ImpactEffectShield= Shields

If those are true, I am not sure where droids would fall under.
