To direct the Inspector General of the Department of Defense to conduct an investigation into the withdrawal of the United States armed forces from Afghanistan, and for other purposes.

The investigation must analyze (1) the extent to which, and reasons why, U.S. Humvees, helicopters, artillery, and drones ended up in the Taliban's possession; (2) the extent to which Afghan forces in possession of U.S. equipment entered Iran with such equipment; and (3) the effectiveness of the evacuation of U.S. and allied personnel.
