This guy right here:
Meet "Hector," a MkXXXIII Bolo. Hector is a fully sentient 32,000 ton main battle tank with primary armament consisting of three 200cm Hellbore turrets, which are essentially plasma cannons whose ammunition consists of steel-jacketed slivers of high-pressure, frozen deuterium, which is heated and compressed to the fusion point by powerful magnetic fields and extreme acceleration; the result is essentially a massive Castle Bravo-scale thermonuclear blast compressed into a pencil-thin beam of pure
boom, and their firepower is measured in multiple megatons per second. They can maul an enemy fleet at greater distances than from the Earth to the Moon, or instantly slaughter anything short of another Bolo or unit of equivalent power. Secondary weapons consist of sixteen 30cm Hellbore infinite repeaters, four 240cm howitzers and ten 40cm mortars for indirect fire, various flavors of antipersonnel flechette cannons for those tender, intimate moments, and for that special touch that means so much, a VLS-array loaded with a wide assortment of thermonuclear party favors. It can deploy from orbit, has a top land sprint-speed of better than 100km/hour, carries a contingent of non-sentient Golem tanks for extra fire support, and drones and small aircraft for close-air support and surveillance. For all intents and purposes, it is a land-mobile, fusion-powered aircraft carrier that can actually
fly, using its contragrav systems to reach a top airspeed of about Mach 1 when it really needs to hustle somewhere in a hurry. It is referred to as a Planetary Siege Unit. An earlier, less-capable, more primitive mark of Bolo was actually able to burrow out of 200 meters of concrete and backfill and, while hideously damaged, dig a tunnel for several klicks underground while running on its nearly-flat batteries alone. It is a white knight, perfectly loyal, vicious in war, yet compassionate and merciful wherever possible, and is an exemplar of the best traits Humanity has to offer.
It enjoys composing poetry and music.
Also, since I'm just wishing, one of these:
