The NATO Training Mission Afghanistan (NTM-A), a U.S. Army initiative, is a multinational organization aimed at training, advising, and assisting the Afghan National Defense and Security Forces (ANDSF). Established in 2003 as part of Operation Enduring Freedom, it operates under the broader NATO Resolute Support Mission. The mission aims to build the capacity of ANDSF to maintain security within Afghanistan and enable self-sustainability. It is a key component of international efforts to promote stability in the region following the withdrawal of coalition forces.
