Appropriate artillery for Russian Battalion?

[Imp]

Without looking I would say probably rare for the partisans to have arty, perhaps 1-2 small mortar or small as in 37 field gun. So that only leaves an infantry & tank com reinforced so for a meeting the 152 is to much. Or at least tone it down to a 122 though I suppose you could keep the 155 if used exclusivly for CB as in its not under your control just doing its own thing.
