Side note here, since many people mentioned LeiG as an axis analogue of pak howie, i would mainly disagree, but admit that are some common points when comparing 2 LeiG vs 1 pak howie performance. Ideally axis stock indirect fire (OST mortar, OKW LeiG) are early options with some midgame presence, pak howie is a mid game unit with late game presence.
Pack Howie:
Range 40-80 (40 near / 60 mid / 80 far)
Damage: 80 (68 near / 40 mid / 20 far)
AOE: 5 (1.5 near / 3 mid / 4.5 far)
Reload: 7
Leig:
Range 40-80 (40 near / 60 mid / 80 far)
Damage: 80 (68 near/ 40 mid / 20 far)
AOE: 4 (0.75 near / 1.5 mid / 2.25 far)
Reload: 6.5-7.1
I don't see how you avoid the comparison, these units are very similar in function and role. Outside of these stats, the Pack has more penetration and better ability unlocks, while the Leig is cheaper, has better vet, and scatters less.
