The Type 87 is a Japanese self-propelled anti-aircraft gun, roughly similar in concept to the Flakpanzer Gepard to replace the M15 and M42 in Japanese service. Initially designed to utilize the Type 61 hull, development was switched to the newly available Type 74 hull to keep it up to date. It is commonly nicknamed as "Guntank" by Japanese crews after the similar-looking mecha in the Mobile Suit Gundam series.

Introduced in Update 1.67 "Assault", the Type 87 is incredibly similar to the German Flakpanzer Gepard, using the same 35 mm Oerlikon KDA autocannons with a similar turret layout. The Type 87 performs fairly well at its rank, being able to effectively engage aircraft thanks to its high rate of fire, quick turret traverse, and radar systems. It is also capable of fighting lightly armoured tanks such as most IFVs (BMP, Warrior, Bradley, etc.), destroying them in seconds with its rapid-firing guns. The Type 87 is also extremely proficient at shooting down helicopters - the AH-1G is a common nuisance that the Type 87 has no difficulty destroying. However, against more modern helicopters (Ka-50, AH-64, etc) that often stay at longer ranges, the Type 87 is harmless and the only thing the tank commander can do is take notice of the laser warning system, deploy smoke, and take cover.
