Arme Automatique Transformable Modèle 1952
from Girls' Frontline
Origin
France
The AAT-52 (full designation in French: Arme Automatique Transformable Modèle 1952, "Transformable automatic weapon model 1952"), also known as "La Nana" is one of the first French-produced guns of the post-World War II era. It was manufactured by the French government-owned MAS company. The AAT-52 is still used today as a vehicle-mounted weapon due to large quantities in service, but has been replaced in the helicopter role by the Belgian FN MAG, starting with the EC 725 Caracal of the Special Operations units and the Air Force Search and Rescue teams. The AAT-52 is largely supplemented in infantry use in favour of the lighter FN Minimi. The AA-52 is still in use in Afghanistan.
