During the 2001 invasion of Afghanistan, the Night Stalkers from 2nd Battalion supported two task forces established in early October 2001: Dagger and Sword. (Their unit in TF Sword was designated Task Force Brown.) In the evening of 18 October into 19 October 2001, two SOAR MH-47E helicopters, escorted by MH-60L (Direct Action Penetrators) (DAPs), airlifted U.S. troops from the Karshi-Khanabad Air Base in Uzbekistan more than across the Hindu Kush mountains into Afghanistan.
