The Iraqi Army is the land warfare branch of the Iraqi Armed Forces, responsible for defending Iraq's sovereignty and maintaining security. It was officially established in 1921 and has undergone significant changes, especially after the fall of the Saddam Hussein regime in 2003. The army has been involved in various conflicts, including the fight against the Islamic State (ISIS) in recent years. The Iraqi Army is composed of various units, including infantry, armored, and special forces. It works alongside other branches of the military, such as the Iraqi Air Force, to ensure national defense. The army has received training and support from international partners, including the United States and NATO, to enhance its capabilities and effectiveness.
