Spider(tank): This one would not have wheels but actual walking legs. Slow tank but can move in weird ways such as climbing vertically and or utilizing magnetic reverberator as grappler to scale walls or sides of ships. The magnetic reverberator would also be a tool for assembly(aka ship repair) as well as what you’d expect from a defencive unit(Railgun).
Centipede(hauler/miner): Collapsable frame that expands and deploys additional wheels with each explansion in a way simular to landing gear. The head would be equpped with mining lance that can act as moderate defense or cut into the ground. Unlike the other landing craft, this one comes with a limpit controller that collects mineral fragments or anything lootable nearby.
edit: just throwing out some interesting ideas for this
