Bolo (Cybertank), Mark XXIV Cognitus

Scale: 1/300
Source: Bolo series created by Keith Laumer.
The Bolo, Mark XXIV (Cognitus), introduced in 2962, was the first genuinely autonomous Bolo. Where previous Marks had allowed tactical autonomous direction, the Mark XXIV's improved personality center and id integration circuitry permitted truly independent, strategic self-direction.
