The structure of the Israel Defense Forces (IDF) differs from most armed forces in the world in several ways. These include the close integration of air, ground, and sea forces, and the conscription of women. Since its founding, the IDF has adapted to match Israel's unique security situation. The IDF is one of Israeli society's most prominent institutions, influencing the country's economy, culture and political scene. Following 1967, the Israel Army has had close military relations with the United States Army, including development and cooperation, such as on the F-15 jet, and the Arrow missile defense system.
