Now for the questions
-I know I need to get a transport of some sort for my "adeptus" stormtroopers, but I'm not sure which would be best.
-Would Land Raiders for the Inquisitors be overkill or just what the force needs for anti-armor.
-I do have Marines and plenty of Guard that can join this force as well, but which is better?
-Debating on the next purchase for this force: Arch-flagellants or Penitent Engine (or another inquisitor)
-Anything else? (power could go out here from t-storm)
