The Type 61 or M61 main battle tank is a type of ground weapon in the anime series Mobile Suit Gundam. It was fielded by the Earth Federation in U.C.0061 and saw service up until at least U.C. 0079. The Type 61 tank featured dual 150mm cannons and a 12.7mm machine gun, as well as eight smoke dispensers. There were also a wide selection of variants made for transport and troop deployment.Technology & Combat CharacteristicsThe Type 61 in many ways follows the traditional layout defined centuries ago, with the notable exception of having twin cannons. An automatic loader is located at the bottom of the turret basket to feed both guns, with turret crew compartment on top of that loader. Turret crew in baseline models includes a gunner and a commander, who are cut off from the driver's compartment in the forward hull by the autoloader. Minimal close-in defenses against infantry or aircraft are primarily provided by a 12.7mm machine gun mounted on the commander's cupola; the stowage basket at the turret's rear can serve as a platform for another 7.62mm machine gun, but a crewman must exit the tank altogether to operate that second machine gun, or alternatively another personnel outside of the tank's crew complement (an accompanying infantryman, for example) can man the platform.After the Zeon forces introduced the Zaku as a mainstay war machine in the One Year War, the Type 61 acquired a reputation of obsolescence, as Minovsky interference heavily undermined the tank's tactical communication abilities and also reduced its observation and targeting capabilities to line-of-sight optics. Another disadvantage was that mobile suits were more agile and could outmaneuver armored units at close distances, sometimes dodging APDS rounds outright. Size and angle of attack were also problems, as Zakus were easily able to target the vehicle's thinner top armor, whereas the Type-61 lacked enough gun elevation to reliably hit key components of the Zaku at close range.
