Yes. They should be used to provide operational mobility for the Light Bn to move between AOs.
In a tactical sense they be likely used to carry the sustainment items, ie rucks, additional ammo, water, equipment to charge batteries etc.
I would expect them to also be used by the mortars, ATGMS, DFS etc to get themselves and the systems into positions and then pull back and be cached.
I would not be surprised to see the Bns start trying to figure out how to mount weapons on them for use as a fire base but given the Bns won’t actually own the vehicles that will likely be limited.
