This is the Irrational Designs model, via Shapeways.
Looks like a Class 4 (large) vehicle to me.
The "oval" gun probably isn't an autocannon or high-velocity cannon, and is too large to be MDC or HKP, and lasers don't need long barrels
so I went with DFFG.
The other weapons are the rocket pack on the turret top, the machinegun turret on the main turret rear, and the machinegun in the forward hull.
I didn't know what the "strapped on tubes" on the turret side were, so made them targeting systems.
