There's more of a case for having mobile HMG units. Particularly is they have a full crew.
The German MG42 weighed 25 lbs
Tripod weighed 45 lbs
250 round ammo boxes weighed 18 lbs each
The MG42 fired 250 rounds in 12 seconds of continuous fire.
Here's a crew description:
A full German MG42 machine gun squad consisted of six men in total, although in combat six men supporting one machinegun would rarely remain together as a close knit unit.
First man: Usually a junior NCO, fired the gun and had a pistol as a back up.
Second man: Carried the ammunition and assisted the firer by helping to load and feed the ammunition, also had a pistol as a back up.
Third man: Carried the spare barrels and ammunition and was also a spotter for the crew and he had a KAR98 rifle as a back up.
Fourth man: Carried the tripod and had an MP40 sub machine gun as a back up.
Fifth man: Carried entrenching tools and extra ammunition an had a KAR98 rifle as a back up.
Sixth man: Carried gun oil, cleaning cloths, and binoculars and he also had a KAR98 rifle as a back up weapon.

If BA does model mobile mortars and or HMGs, they should have limited ammo.
