Task Force 88 ( anti - terrorist unit ) Task Force 88 is an American special operations unit formed since 11 September 2001 , of which little is publicly known . It is described as a " hunter - killer team " with its core made up of Delta Force , 75th Ranger Regiment Rangers , members of the USAF 24th Special Tactics Squadron , and Navy DEVGRU operators . The unit was reported to be responsible for both the cross border raid into Syria from Iraq in October 2008 that resulted in eight deaths including Abu Ghadiya and several US operations in the Horn of Africa targeting al Qaeda . History as Task Force 145 . Since the invasion of Iraq , the unit went through a number of changes of designation . Task Force 20 was amalgamated with Task Force 5 ( formerly Task Force 11 / Task Force Sword ) in Afghanistan in July 2003 , and became Task Force 21 . It was then redesignated Task Force 121 , and later as Task Force 626 , Task Force 145 , and Task Force 88 . Neville notes that he omitted the ' current ' ( c . 2008 , time of writing ) designation of the unit . However he did say that it was also known obliquely as Other Coalition Forces – Iraq ( OCF - I ) , ' a wry reference to the CIA unit of the moniker OGA . ' It was a combined U . S . and British military special forces provisional grouping specifically charged with hunting down high - value al - Qaeda and Iraqi leadership including Osama bin Laden and , prior to his death on 7 June 2006 , Al - Qaeda in Iraq leader Abu Musab al - Zarqawi . It is believed that the Task Force played a role in the medium altitude strike mission that killed al - Zarqawi just outside Baqubah . The Task Force was charged with disrupting al - Qaeda operations in Iraq and , to a lesser extent , Afghanistan . The action arm of the task force was made up of operators from 1st Special Forces Operational Detachment - Delta , United States Naval Special Warfare Development Group ( ' DEVGRU ' ) , British Special Air Service , British Special Boat Service and soldiers from the 75th Ranger Regiment . Members of the CIA ' s elite Special Activities Division paramilitary unit were also believed to be an important part of the group . Support elements include the Army ' s 160th Special Operations Aviation Regiment ( Night Stalkers ) , the Air Force ’ s 24th Special Tactics Squadron , and British paratroopers from the Special Forces Support Group . The unit was operating up until at least January 2007 ; it is not clear whether it is still operational with the U . S . drawdown from Iraq . In January 2007 Task Force 88 established a subsidiary task force , Task Force 17 , in addition to an existing task force , Task Force 16 . Task Force 17 was established to ' counter Iranian influence . ' Task Force 17 was to be made Initially Operationally Capable as of ' NLT 15 January 2007 and Full Operational Capability ( FOC ) will be in place NLT 15 February 2007 . ' Operations . The task force is known to operate very autonomously . In their only publicly known operation they reportedly conducted several raids without requiring approval from higher authorities . The task force was also responsible for the elimination of Abu Musab al - Zarqawi . Over 18 months beginning in early 2007 , the task force reportedly arrested 3 , 500 terrorists in Baghdad and killed several hundred others . Thus , al Qaeda bomb attacks went down from an average of 150 per month ( killing monthly 3 , 000 people ) to about two . During the campaign , six SAS troops were killed and 30 injured . Delta Force suffered an overall 20 percent casualty rate . During operations in Al - Anbar province , TF88 operatives entered the insurgent controlled city of Haditha , several times finding Zarqawi ' s hideouts . Their raids found eggs still cooking , just missing the terrorist leader . Based on this current and actionable intelligence , they asked the commander of II MEF ( FWD ) to have to city of Haditha assaulted in order to flush Zarqawi out . The general chose the 3rd Bn 1st Marines , experienced in heavy fighting from Operation Phantom Fury , to assault the city . It is not clear what the reduced U . S . military role following the U . S . – Iraq Status of Forces Agreement and associated drawdown to purely advisory operations has had on the task force ' s operations . Organization . Organization as of October 2006 . TF 145 , or TF 88 as it may now be known , was commanded by a colonel ( the commanding officer of the Army ' s Delta Force ) and is based at five locations across Iraq . Its task organization drew on every unit of the U . S . Joint Special Operations Command ( JSOC ) as well as on the CIA ' s Special Activities Division and British special operations forces . The headquarters element , which included the majority of the task force ' s many aviation and intelligence assets , was based at Balad Air Base between Samarra and Baghdad ; the four elements that it controlled , each commanded by a lieutenant colonel or equivalent , were spread across the country . Task Force Center is probably co - located with TF 145 ' s headquarters element at Balad , but it could also be based at Camp Liberty , since it is responsible for the Baghdad region . TF Center is based around a direct - action squadron ; the three Delta Force squadrons and SEAL Team 6 appear to rotate through this position . It is also supported by a rotating company - sized element of the 75th Ranger Regiment and elements of the 160th Special Operations Aviation Regiment . TF Center has taken casualties in the Yusufiya area , where one of its helicopters was shot down in spring 2006 . Task Force West is structured similarly to TF Center in that it has a company - sized force protection element from the 75th Rangers and is based around a battalion - sized direct action unit that can at any given time be a Delta Force squadron or Naval Special Warfare Development Group ( known also as SEAL Team 6 ) . It seems that these units rotate every three to four months . TF West is responsible for operations in Anbar , where it is known to have been active at various times in Fallujah , Qaim , Husayba , and Ramadi ; Delta Force lost nine operators during combat in Husaybah , Qaim and Ramadi . It is likely that TF West is based either at Camp Asad or Camp Taqaddum . Task Force North is organized differently : it is based around a full battalion of the 75th Rangers ( the position rotates among the three battalions ) , with a company - sized element from Delta Force acting in support . TF North was based at FOB Marez in Mosul . Task Force Black / Knight . Based in the Baghdad area , TF Black ( which was supported by Parachute Regiment members of the Special Forces Support Group ) is based around a squadron of the British army ' s 22 Special Air Service Regiment , with integrated units from the Special Boat Service and US 1st SFOD - D ( Delta Force ) . It has participated in operations in the Baghdad area when British or Canadian hostages are involved . Operation Marlborough in July 2005 , when the SAS killed three insurgent would - be suicide bombers , was also carried out by this unit in the Iraqi capital . Sergeant Jon Hollingsworth , killed in Iraq with the SAS , was decorated for his service in this unit . Reportedly , TF Black has removed or killed 3 , 500 insurgents from the streets of Baghdad . With the removal of these insurgents , the number of bombings has been reduced from 150 per month to about 2 per month . In October 2004 , all SAS personnel in Iraq including Task Force Black were banned from handing over suspects to the US forces if the suspects were going to be taken to a US interrogation center due to the fact of the bad reputation those centers were getting . Another setback for the task force was during the Second Battle of Fallujah when the SAS was banned from going into the city alongside its American counterpart because of the pressure that the government was feeling from the unpopularity of the war .
