1947–1949 Palestine war
The nations of the Arab League that joined in the war against Israel were Egypt, Transjordan, Iraq, Lebanon, and Syria (there was a smaller force from Saudi Arabia and Yemen under Egyptian command). Despite having the League to bind them, at the start of the war there was no single League commander. Each country mobilized its own force for its own goals. The force was thus not one League force but a collection of forces. The final force from the Arab League, the Arab Liberation Army, was a force of 4,000 volunteers from across the Middle East which worked out of Syria. While the nations of the Arab League surrounded Israel, they did so as different countries.
