For Mournfangs, an ideal matchup for us would be to charge them with two units of DGs. 18 attacks from DGs, 12 hits, 8 wounds, 2-3 saves. 6 Knights, 4 hits, 4 wounds, 1-2 saves. That's 7-8 wounds for us, enough to drop 2.
On the return attacks, 3 MFs hit 6 times, wound 4 times at -2, we make 2-3 saves. 3 Ogres attack 9 times, 4-5 hits, we save all but one. So, at worst, we lose one DG. We win combat convincingly and should break them even with a re-roll.
I think we want to be directing the 5-man knight units into the Gnoblar units (they'll have to take dangerous terrain tests... clever Ogres).
Sabretusks we hit with whatever we can.
Captasi go after the Ironblasters.
We stall the Irongut units for as long as possible and then decide whether to hit them or not.
