Here's a superbly painted platoon of the Topgun Marketing 15mm Grav Tanks, for your viewing pleasure:

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.
They were 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.
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.
These would be great for a game of Striker, on the tabletop, using 15mm vehicles and infantry.
As you can see from the photo, they are top of the line in terms of Grav Tank technology of the future.
