Here's a platoon of Topgun Marketing 15mm Grav Tanks, superbly painted by Richard Meaden, who did a very nice job of creating a unique camo. scheme, numbering system, and unit badge for these ultra-high tech vehicles:

These are the Type 9 Light Grav Tanks with the smooth-hulled finish, but they can also serve as Medium Grav Tanks, with short-barreled weapons, if you prefer.
Check the links for some more great photos of these, from different angles, as well as some unpainted vehicles with the AADS, or Active Armor Defense System, which is an automated vehicle self-protection system of the future.
We think they fit the bill for ultra-high tech Grav Armored vehicles, when nothing but the best will do to support your planetary assaults, or armored thrusts, halfway around the globe.
