A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs).

The United States Invasion of Panama, codenamed Operation Just Cause, lasted over a month between mid-December 1989 and late January 1990. It occurred during the administration of President George H. W. Bush and ten years after the Torrijos–Carter Treaties were ratified to transfer control of the Panama Canal from the U.S. to Panama by January 1, 2000. The primary purpose of the invasion was to depose the de facto Panamanian leader, general and dictator Manuel Noriega. Noriega, who for a long time worked with the Central Intelligence Agency, was wanted by the United States for racketeering and drug trafficking. Following the operation, the Panama Defense Forces were dissolved and President-elect Guillermo Endara was sworn into office. The United Nations General Assembly and the Organization of American States condemned the invasion as a violation of international law.

The United States Army Special Forces, colloquially known as the "Green Berets" due to their distinctive service headgear, are a special operations force of the United States Army that are designed to deploy and execute nine doctrinal missions: unconventional warfare, foreign internal defense, direct action, counter-insurgency, special reconnaissance, counter-terrorism, information operations, counterproliferation of weapons of mass destruction, and security force assistance. The first two missions, unconventional warfare and foreign internal defenses, emphasize language, cultural, and training skills in working with foreign troops. Other Special Forces missions, known as secondary missions, include: combat search and rescue (CSAR), counter-narcotics, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peacekeeping, and manhunts. Other components of the United States Special Operations Command (USSOCOM) or other U.S. government activities may also specialize in these secondary missions. The Special Forces conduct these missions via seven geographically focused groups. Many of their operational techniques are classified, but some nonfiction works and doctrinal manuals are available.
The 1st Special Forces Operational Detachment–Delta, commonly referred to as Delta Force, Combat Applications Group (CAG), "The Unit", or within JSOC as Task Force Green, is a special operations force of the United States Army, under operational control of the Joint Special Operations Command.

The War on Terror, also known as the Global War on Terrorism and U.S. War on Terror, is an ongoing international military campaign launched by the United States government following the September 11 attacks. The targets of the campaign are primarily Islamist groups located throughout the world, with the most prominent groups being Al-Qaeda, the Islamic State, the Taliban, Tehrik-i-Taliban Pakistan, and the various franchise groups of the former two organizations. The naming of the campaign uses a metaphor of war to refer to a variety of actions that do not constitute a specific war as traditionally defined. U.S. president George W. Bush first used the term "war on terrorism" on 16 September 2001, and then "war on terror" a few days later in a formal speech to Congress. In the latter speech, George Bush stated, "Our enemy is a radical network of terrorists and every government that supports them." The term was originally used with a particular focus on countries associated with al-Qaeda. The term was immediately criticised by such people as Richard B. Myers, chairman of the Joint Chiefs of Staff, and more nuanced terms subsequently came to be used by the Bush administration to publicly define the international campaign led by the U.S. While it was never used as a formal designation of U.S. operations in internal government documentation, a Global War on Terrorism Service Medal was issued.
