I was setting up a Finn (defense) scenario recently with lots of exposed woodlines, and dreamed of a mtr in my OOB that was not there. Checking Chapter H, I was surprised to find they only field a huge 120mm in their arsenal. No "meatball throwers", no 81mm. I can't be certain, but I think I may have played a Finn scenario or two where they have German 81mm in their OOB, but can't recall at all any that fielded a SW-sized mtr.
Knee-deep in your Finn Pack research/design, have you found this to still universally be the case? With a huge Finns Only pack being undertaken, I'm wondering if any other mtr/MTR usage by them has been uncovered? With the research that went into Chapter H, I can only assume that they manufactured none but the 120mm....but were 'gifted' mtrs/MTRs used more prevalently than past Finn scenarios suggest? Or, was mortar usage simply not in their style of warfare? Especially with set-position, Mannerheim Line scenarios being researched/designed, it would seem to be a gimme that they would have had mortars in their defence. Or maybe not.
