The KDB-2 Bullfrog is a unique all-terrain assault transport with significant anti-aircraft capability. Kiev-based Kazminov Design Bureau all but clinched its monopolistic role as the Soviet Union's favored manufacturer-designer of military vehicles with this particular model, which has proven itself time and again in more than seven years' worth of fierce combat worldwide. It features twin PVS 5-7 Tucha 23mm anti-aircraft cannon as its main armament. Deployment of the Bullfrog only requires either a War Factory or a Naval Yard and each Bullfrog costs $900.
