To cement his power and subdue the population of Somalia, Aidid and his militia seize Red Cross food shipments, coercing the cooperation of the people, while the U.N. forces are powerless to directly intervene. Outside Mogadishu, Rangers and Delta Force operators capture Osman Ali Atto, a warlord selling arms to Aidid's militia. Shortly thereafter, a mission is planned to capture Omar Salad Elmi and Abdi Hassan Awale Qeybdiid, two of Aidid's top advisers.
The U.S. forces include experienced men as well as new recruits, including Private First Class Todd Blackburn and a desk clerk going on his first mission. When his Lieutenant is removed from duty after having an epileptic seizure, Staff Sergeant Matthew Eversmann is placed in command of Ranger Chalk Four, his first command.
The operation is launched and Delta Force operators successfully capture Aidid's advisers inside the target building. The Rangers and helicopters escorting the ground-extraction convoy take heavy fire, while SGT Eversmann's Chalk Four is dropped a block away by mistake. Blackburn is severely injured after falling from one of the Black Hawk helicopters, so three Humvees led by Sergeant Jeff Struecker are detached from the convoy to return Blackburn to the U.N.-held Mogadishu Airport.
SGT Dominick Pilla is shot and killed just as Struecker's column departs, and shortly thereafter Black Hawk Super-Six One, piloted by CWO Clifton "Elvis" Wolcott, is shot down by a rocket-propelled grenade (RPG) and crashes deep within the city. Both pilots are killed, the two crew chiefs are wounded, and one Delta Force sniper on board escapes in another helicopter.
The ground forces are rerouted to converge on the crash site. The Somali militia erects roadblocks, causing LTC Danny McKnight's Humvee column to get lost, while sustaining heavy casualties. Meanwhile, two Ranger Chalks, including Eversmann's unit, reach Super-Six One's crash site and set up a defensive perimeter to await evacuation with the two wounded men and the fallen pilots. In the interim, Super-Six Four, piloted by CWO Michael Durant, is also shot down by an RPG and crashes several blocks away.
With CPT Mike Steele's Rangers pinned down and sustaining heavy casualties, no ground forces can reach Super Six Four's crash site nor reinforce the Rangers defending Super Six One. Two Delta Force snipers, SFC Randy Shughart and MSG Gary Gordon are inserted by helicopter to Super Six Four's crash site, where they find Durant still alive. The crash site is eventually overrun, Gordon and Shughart are killed, and Durant is captured and taken to Aidid.
McKnight's column gives up the attempt to reach Six-One's crash site and returns to base with their prisoners and the casualties. The men prepare to go back to extract the pinned down Rangers and the fallen pilots and MG Garrison sends LTC Joe Cribbs to ask for reinforcements from the 10th Mountain Division, including Malaysian and Pakistani armored units, to mobilize as a relief column.
As night falls the Somali militia launch a sustained assault on the trapped Americans at Super Six One's crash site. The militia is held off throughout the night by strafing runs and rocket attacks from AH-6J Little Bird helicopter gunships of the Nightstalkers, until the 10th Mountain Division's relief column is able to reach the site. The wounded and casualties are evacuated in the vehicles, but a handful of remaining Rangers and Delta Force soldiers are forced to run from the crash site back to the stadium, in the UN Safe Zone.
The closing credits detail the results of the raid: 19 American soldiers were killed, with over 1,000 Somalis dead. Durant was released after 11 days of captivity. Delta Force snipers Gordon and Shughart were the first soldiers to be posthumously awarded the Medal of Honor since the Vietnam War. On August 2, 1996, Aidid was killed in a battle with a rival clan. General Garrison retired the following day.
