The Spiller Group's Rook is a multi-purpose tracked, armored vehicle that resembles a miniature bulldozer. Operators can deploy on the front and rear of the Rook shielded by armor that can stop rifle rounds. Its most interesting feature is an armored deployment and rescue platform, with hydraulic lift. The platform can be raised to a second-floor window, and is shielded by armor that has gunports. There's a sliding door in the armored shield, so officers can deploy forward through the shield. Other features on the Rook include a breaching, penetrating arm with a camera, a vehicle extraction attachment, a grapple bucket for removal of barriers and obstacles, and a tactical video recording system. The Rook is operated by a joy stick.
