Bullfrog

the CB-43 Bullfrog is Headman's amphibious infantry fighting vehicle. it was designed to allow a breakthrough in enemy defenses on beaches and unload troops into the flanks of the defending enemies and then drive off with those troops to encounter any sudden counter attack. it has only 60mm of armor but is fitted with a 30mm auto cannon with a semi and full auto burst. the semi auto is used to one shot troops while the full auto burst is used on light armored vehicles. for medium and heavy armored vehicles, it uses the tunka rocket launcher with thermite warheads to melt and send those molten metal flying inside striking and injuring the crew.
the bullfrog can reach speeds of 40 km/h. some were used on land as normal infantry support. the treads on the bullfrog were designed to propel the vehicle through water and double as all terrain
