Combined Security Transition Command – Afghanistan

The Combined Security Transition Command – Afghanistan (CSTC-A) was a U.S.-led military organization responsible for overseeing the development of Afghanistan's national security forces, including the army and police. It managed training, mentoring, and equipping Afghan security institutions to ensure their independence and stability. CSTC-A coordinated efforts among various military, government, and international partners to build a sustainable security system, aiming for Afghanistan to maintain peace and security without external assistance. It played a critical role during the transition period leading up to the withdrawal of NATO forces in 2021.
