Given UKF has no stock mortar, I think the 81mm is good.
I wouldn't object to the Pack Howie. I think the Mortar HT might be fuel overkill though.
IMO pack howie might be a bit too strong though lol. Although I do wish a
doctrinal unit would at least be on par with its german counterpart. A copypaste (at least statwise) of the german mortar or even the soviet mortar would be preferable IMO.
And I'd still like to see vehicle repair replaced with that ability on the halftrack from Ardennes Assault that let it repair in a radius or whatever. Much more unique ability and that would free up the commander to have
at least 1 offmap type ability other than callin units, since right now 4 out of 5 (if you count assault tommies) slots are taken up by call-in units that aren't even anything super unique to other factions (read: they're making up for brits' gaping holes in their unit roster).
Warspeed still isn't working on the callin vehicles as far as I know.
