The Bullfrog is an experimental design from Bulldog Enterprises based on their Bulldog medium tank. It has not so far been a commercial success, primarily due to its cost.

         The Bullfrog is considered a standard tank design. Mounting only one heavy weapon and a few secondary weapons, it is a jack-of-all-trades rather than a specialist at certain types of missions.
         Bulldog Enterprises developed this tank's large laser to lower their production costs by not having to purchase equipment from other companies. The laser is a fairly typical design, using a powerful energy capacitor to release the energy held in a krypton gas container. Other systems were tested, but the gas laser was the most effective.
         Bulldog did not have the time or money to also design the short-range missile racks, and so they made a deal with Hover Tech, who provided Bulldog with the plans to produce the missile system. The HoverTech Hex SRM system is also used on many other vehicles, as well as on a few 'Mechs. Similarly, the Delta Dart LRM launcher added for this upgrade is an off-the-shelf component.

No variants of the Bullfrog have been observed to date.
