Grav-mobile infantry squad with lift IFV
Grav artillery vehicle with infantry squad and support gun team as a security element
Foot infantry squad supported by a grav strike skimmer (which could also be a strafighter easily enough)
All the grav vehicles are based on 1.5" washers with a Hawk Wargames flight post solidly rooted in a lump of sculpting putty. The vehicles themselves have Hawk widgets attaché dto them, which allows them to be easily mounted or dismounted as needed to play, store, or transport them. I heartily recommend this basing technique for grav vehicles, especially the heavier metal ones from GZG.
