Created in June 2006 by President of the United States George W. Bush, the Task Force on New Americans is an interagency initiative to help immigrants learn English, embrace the common core of American civic culture, and fully become American.
 Established within the Department of Homeland Security, Secretary Michael Chertoff serves as Chair of the Task Force.
 Membership includes representatives from 12 Cabinet-level departments and a technical working committee of eight additional federal agencies.
 Alfonso Aguilar, Chief of the Office of Citizenship at U.S. Citizenship and Immigration Services (USCIS), serves as Chair of the Task Force’s technical committee.
 Since it was established more than three years ago, the Task Force has worked to develop interagency initiatives to help immigrants settle in their new country and maximize the use of federal resources in promoting integration.
 By providing technical resources to communities and organizations, encouraging volunteerism, developing effective training methods, conducting targeted research efforts, and providing recommendations to the President, the Task Force has sought to encourage successful immigrant assimilation in a comprehensive manner.
The Battle of Osan (Korean: 오산 전투 ) was the first engagement between United States and North Korean forces during the Korean War, on July 5, 1950.
 Task Force Smith, a U.S. task force of 400 infantry supported by an artillery battery, was moved to Osan, south of the South Korean capital Seoul, and ordered to fight as a rearguard to delay advancing North Korean forces while additional U.S. troops arrived in the country to form a stronger defensive line to the south.
 The task force lacked both anti-tank guns and effective infantry anti-tank weapons, having been equipped with obsolescent 2.36-in.
 rocket launchers and a few 57 mm recoilless rifles.
 Aside from a limited number of HEAT shells for the unit's 105-mm howitzers, crew-served weapons capable of defeating the T-34 Soviet tank had not been distributed to U.S. Army forces in Korea.
The Korean War (in South Korean Hangul: 한국전쟁 ; Hanja: 韓國戰爭 ; RR: "Hanguk Jeonjaeng " , "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁 ; Hancha: 祖國解放戰爭 ; MR: "Choguk haebang chǒnjaeng " , "Fatherland Liberation War"; 25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States).
 The war began on 25 June 1950 when North Korea invaded South Korea.
 The United Nations, with the United States as the principal force, came to the aid of South Korea.
 China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
Task Force Shield was set up by the Coalition Provisional Authority in 2003 to provide security for Iraq's critical oil infrastructure.
 The task force was originally composed of a small team of American military personnel, contractors from the UK-based firm Erinys International, and Iraqis hired, trained and supervised by Erinys.
 The Iraqi force trained by Erinys was called the Oil Protection Force (OPF).
 After the Coalition Provisional Authority transferred control of Iraq to the Interim Government, the OPF became a subordinate element of Iraq's Ministry of Oil.
 The Ministry of Oil did not renew the Erinys contract.
 Task Force Shield was disbanded in 2005.
 In April 2006, the Office of the Special Inspector General for Iraq Reconstruction published a report on the activities of Task Force Shield.
 The report determined that Task Force Shield was ultimately unsuccessful and found that there were indications of potential fraud.
Task Force Faith, also known as Task Force Maclean (and by its official designation, Regimental Combat Team 31 (RCT-31)) or the Polar Bear Regiment (), was a United States Army unit destroyed in fighting at the Battle of Chosin Reservoir during the Korean War between 27 November – 2 December 1950.
 It comprised primarily infantry, artillery, and tank units from the 7th Infantry Division, numbering approximately 3,000 soldiers.
 Of these, about 600 were KATUSAs (Korean Augmentee To the U.S. Army).
 The name Task Force Faith was originally coined by a U.S. Army historian; however, the unit was never known by this name.
 RCT-31, which consisted of the 31st Infantry Regiment and supporting units, had the 1/31 Infantry detached and the 1/32 Infantry (from the RCT-32) added, and the designation RCT-31 was never changed.
The President's Task Force on 21st Century Policing was created by an executive order signed by United States President Barack Obama in December 2014.
 Obama created it in response to the unrest in Ferguson, Missouri following the shooting of Michael Brown by a police officer there.
 The eleven members of the task force include academics, law enforcement officials, and civil rights activists.
 The co-chairs of the task force are Philadelphia police commissioner Charles H. Ramsey and George Mason University professor of criminology, law and society Laurie Robinson.
 On March 2, 2015, the task force released its interim report, and on May 18 of that year, it released its final report.
 The final report called for, among other things, more data on police shootings and on civilians' attitudes toward the police, as well as for the removal of policies that reward police who produce more arrests and convictions.
 In another report released a year later, the task force released an update saying that at least nine states and cities in the United States had adopted the task force's recommendations.
 However, because there are 18,000 police departments in the United States, some members of the task force, as well as President Obama himself, have expressed frustration with the slow rate at which its recommendations have been adopted.
