Yes. & the rank of the generals in neighboring provinces matter.
So (if I remember correctly):
Field Marshal attacking a province from a single province: max 12 units.
Field Marshal with a HQ attacking a province from a single province: max 24 units.
Two Field Marshals with an HQ (anywhere, just one) attacking a province from two provinces: max 48 units.
Two Field Marshals and a Lt. General with an HQ in the army attacking a province from three provinces: max 54 units.
P.S. As much as I love seeing those Italians squishified, I almost wish you'd waited for them to mobilize for attack one of your provinces before smashing them! Also, I'm kind of impressed you found the IC to upgrade all your infantry to 1936.
