Military of the Arab League
The Arab League as an organization has no military force, like the United Nations or the European Union, but recently in the 2007 summit, the Leaders decided to reactivate their joint defense and establish a peacekeeping force to deploy in South Lebanon, Darfur, Iraq, Somalia, and other hot spots.

History
The military history of the Arab League is closely linked to the Arab–Israeli conflict. The 1950 Arab Joint Security Pact set out provisions for collective security among the Arab states, but only in 1961 was the Joint Arab Command (JAC) proposed as a unified military command for the Arab League first by the Joint Defence Council, an institution of the Arab League. 

Before the JAC could take shape, a unanimous resolution was passed at the first Arab League summit (January 1964) establishing the United Arab Command (UAC), although the UAC's inactivity following the Samu Incident (1966) and during the Six-Day War (1967) signalled its de facto dissolution.

Arab Liberation Army

The Arab Liberation Army (جيش الإنقاذ العربي Jaysh al-Inqadh al-Arabi), also translated as Arab Salvation Army, was an army of volunteers from Arab countries led by Fawzi al-Qawuqji. It fought on the Arab side in the 1948 Palestine war and was set up by the Arab League as a counter to the Arab High Committee's Holy War Army, though in fact the League and Arab governments prevented thousands from joining either force.

At the meeting in Damascus on 5 February 1948 to organize Palestinian Field Commands, Northern Palestine including Samaria was allocated to Qawuqji's forces, although Samaria was de facto already under the control of Transjordan.

The Arab League Military Committee, with headquarters in Damascus, was responsible for the movements and servicing of the Army. The Committee consisted of General Ismail Safwat (Iraq, Commander-in-Chief), General Taha al-Hashimi (Iraq), Colonel Shuqayri (Lebanon), Colonel Muhammed al-Hindi (Syria) and Colonel Abd al-Qadir al-Jundi (Transjordan).

The ALA was dissolved at the end of the 1948 Arab-Israeli War.
