The M91 Eagle Main Battle Tank is a main battle tank that was designed and currently manufactured in Lanos by the Lanos Armored Vehicle Corporation. It was designed and created to replace the aging M60-series Patton main battle tank and be supplemented by the M60T Sabra main battle tank in Lanosian service. It is named for the Black and While Hawk-Eagle, the national bird of Lanos. Its design allows for operation in South Emmerian environments while maintaining a balance between protection, firepower, and mobility. Weighing in at 56 metric tons in its full combat configuration, the tank is one of the lightest main battle tanks in the world and one of the fastest of its generation. The tank entered Lanosian service in 1998 after years of development and testing. It serves alongside the M60T Sabra in service and is the frontline main battle tank of the entire Lanos Armed Forces. The M91 is the only variant in Lanosian service.


During the 1980s, the M60-series main battle tank was shown to be showing its age compared to other main battle tanks at the time, especially the Emmerian M1 Abrams despite second-line usage of the M60-series tank. Even during the Great Desert War , which Lanos had actively participated in, the National Government and the Armed Forces sought a main battle tank that was suited for the Lanosian terrain and was significantly more modern than the M60. The government undertook the stopgap M60 Phoenix upgrade program for M60-series tanks to get them modernized and to modern ANTO-frontline standard but Lanos needed a new main battle tank. Knowing the Lanosian and South Emmerian environment and terrain precluded tanks such as the M1 Abrams from effective service, the Armed Forces turned to other potential designs for the new Lanosian tank, even home-built sources. Importation of foreign tanks was considered but rejected in favor of producing a Lanosian tank suited to South Emmeria.

However, domestic manufacture of a indigenous Lanosian tank

  • Under construction.
