Tank design 2

Design for a futuristic light tank. My graphics tablet has died, hence the crude mouse-drawn brushwork. A new tablet is in the post.

The "Manta" Light tank is designed for recon / patrol duties or as a cheap main battle tank for low-budget armies. The two crew (driver/commander and systems officer) sit side-by-side in the hull, in front of the fully automated turret.
Armament consists of a 30mm hypervelocity railgun, two 8mm caseless machine guns, and two eight-barrel 40mm grenade launchers mounted in cupolas on either side of the main turret.
The hedgetrimmer-looking thing at the front is a mechanical cutter designed to cut through wire and undergrowth. It has also proved an effective psychological deterrentt to enemy personnel at close quarters.
Armour consists of carbon-nanotube reinforced ceramic tiles between two layers of titanium, with an inner layer of flexible aramid-fibre material. The inner layer of titanium carries a very high-voltage electrical charge - any projectile (solid or plasma) penetrating the first two layers will complete the circuit between the two layers of metal, the resulting high-energy discharge deflecting the projectile.
The drive system consists of two hydrogen-gas turbines in the rear of the hull powering electrical motors in the hubs of the road wheels. The tracks are one-piece bands of carbon-reinforced synthetic composite.
