Iran’s armed forces consists of a multitude of different services, including the Ground Forces, Navy, Air Force, an Air Defense Force which is responsible for providing an anti-aircraft security net, and a law enforcement branch. This structure remains somewhat similar to the Shah-era military structure, save for the Air Defense Force which became its own branch separate from the Air Force in 2008, as well as the Islamic Revolutionary Guard Corps which contains its own ground force, navy, and aerospace force. In addition to the IRGC’s other branches is the Quds Force, which performs asymmetrical warfare abroad, and the Basij, a paramilitary unit. These branches all have personnel equipped with various different types of tactical equipment, with many pieces acquired pre-Islamic Revolution transferring over to the newly formed Iranian Army.
