The Azerbaijani Armed Forces (Azerbaijani: Azərbaycan Silahlı Qüvvələri) is the military of the Republic of Azerbaijan. It was re-established according to the country's Law of the Armed Forces on 9 October 1991.[1] The original Azerbaijan Democratic Republic's armed forces were dissolved after Azerbaijan was absorbed into the Soviet Union as the Azerbaijan Soviet Socialist Republic from 28 April 1920. After the Soviet Union dissolved in 1991–92, Azerbaijan's armed forces were reformed based on Soviet bases and equipment left on Azerbaijani soil.

The armed forces have three branches: the Azerbaijani Land Forces, the Azerbaijani Air and Air Defence Force, and the Azerbaijani Navy. Associated forces include the Azerbaijani National Guard, the Internal Troops of Azerbaijan, and the State Border Service, which can be involved in state defense under certain circumstances.

According to the Azerbaijani media sources, the military expenditures of Azerbaijan for 2009 were set at US$2.46 billion, however according to Stockholm International Peace Research Institute, only $1.473 billion was spent that year. IISS also suggests that the defence budget in 2009 was $1.5 billion. The Ministry of Defence Industry of Azerbaijan supervises the design, manufacturing, regulation and maintenance of military equipment. In the future, Azerbaijan hopes to start building tanks, armored vehicles, military planes and military helicopters.

The Azerbaijani Land Forces (Azerbaijani: Azərbaycan Silahlı Qüvvələri Quru Qoşunları) are the land force component of the Azerbaijani Armed Forces. Since the fall of the Soviet Union, Azerbaijan has been trying to create professional, well trained, and mobile armed forces.

In addition, there are 300,000 former service personnel who have had military service in the last fifteen years.
