In early 1990s Somalia, famine and civil war have gripped the country, resulting in over 300,000 civilian deaths and a huge United Nations peacekeeping operation being sent in. With the bulk of the peacekeepers withdrawn by 1993, the Somali militia have declared war on the remaining UN personnel. In response, United States Army Rangers, Delta Force, and 160th SOAR are deployed to Somalia to capture Mohammed Farrah Aidid, self-proclaimed president of the country. Outside Mogadishu, Rangers and Delta Force operatives capture Osman Ali Atto, a warlord selling arms to the militia of Aidid. Shortly thereafter, a mission is planned to capture Omar Salad Elmi and Abdi Hassan Awale Qeybdiid, two of Aidid's top advisers. The US forces include experienced men as well as new recruits, including PFC Todd Blackburn and a desk clerk going on his first mission. When his Lieutenant is removed from duty as the result of a seizure, Staff Sergeant Matthew Eversmann is placed in command of Ranger Chalk Four, his first command.The operation is launched and Delta Force successfully captures Aidid's advisers inside the target building, but 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. When Blackburn is severely injured after falling from one of the Black Hawk helicopters, three Humvees led by SGT Jeff Struecker are detached from the convoy to return Blackburn to the UN-held Mogadishu Airport. SGT Dominick Pilla is shot and killed just as Struecker's column gets underway, 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. Wolcott and his co-pilot are killed, the two crew chiefs are wounded, and one mortally wounded Delta sniper on board escapes in another helo that makes it back to base. The ground forces are rerouted to converge on the crash site, but the Somali militia throw up roadblocks, causing LTC Danny McKnight's Humvee column to lose its way, while sustaining heavy casualties.Meanwhile, two Ranger Chalks, including Eversmann's unit, reach Super-Six One's crash site, setting 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, crashing 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 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 orders the 10th Mountain Division, including Malaysian and Pakistani forces, 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, however extracting the bodies of Cliff Wolcott and his co-pilot from the downed Black Hawk turns out to be more involved and the column can leave for nearly four more hours. After everyone and any dead soldiers are secured in the vehicles, the convoy leaves. When space inside the vehicles runs short, a handful of remaining Army Rangers and Delta operatives are forced to run from the crash site back to the stadium, in the UN Safe Zone, a journey dubbed the "Mogadishu Mile" by those who ran.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 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 from active duty the following day., Question: Which group is Matthew Eversmann in command of?
