The Hornet class All Terrain Troop Transport is a vehicle designed by Gratuitous Armories (The main manufacturer of weapons for the empire) to perform in environments normal vehicles usually don't. Yet for reasons beyond the Emperor, its rather delicate. Despite that, it does its job. Using a VTOL system for flight and for movement in the water, and a standard engine powered wheels to propel it on land. Capable of holding a section of troops, though its a tight fit, and quite quick, if you can keep it straight. Its first usage was during the wargame between 2 sub-factions within House Gratuitous. It was initially used to blitz down a hill, and before the terrain flattened, its thrusters fired up and took the Hornet to the skies and, after firing 2000 rounds of paint-balls into enemy defenses, landed behind them, and the battle was shortly won.

It has a meager armament of 4 Vulcan G-2s to provide CAS for infantry.
A flipper on the top in case it gets flipped.
A Gyroscope to keep it steady enough.
And a heater.

To control this is simple.
1: Land control. Operates like you'd expect a very slippery car would.
2: VTOL control. Operates like a helicopter, as it has no wings to keep it stable when the nozzle is pointed 90 degrees in either direction. The Gyroscope is also too weak to allow it as well.
