The United States Armed Forces are the military forces of the United States of America. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States.
The Posse Comitatus Act is a United States federal law signed on June 18, 1878, by President Rutherford B. Hayes which limits the powers of the federal government in the use of federal military personnel to enforce domestic policies within the United States. The Act was passed as an amendment to an army appropriation bill following the end of Reconstruction and was updated in 1956 and 1981.
A flight surgeon is a military medical officer practicing in the clinical field of aviation medicine. Although the term "flight surgery" is considered improper by purists, it may occasionally be encountered.
Corps is a term used for several different kinds of organization. A military innovation by Napoleon, the formation was first named as such in 1805. The size of a corps varies greatly, but from two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense.
In military aviation, a wing is a unit of command. In most military aviation services, a wing is a relatively large formation of planes. In Commonwealth countries a wing usually comprises three squadrons, with several wings forming a group. Each squadron will contain around 20 planes.
A medic is a person involved in medicine such as a medical doctor, medical student, paramedic or an emergency medical responder. Among physicians in the UK, the term "medic" indicates someone who has followed a "medical" career path in postgraduate professional training accredited by a College of Physicians, such as cardiology or endocrinology, in contrast to a surgical branch of specialisation accredited by a College of Surgeons.
The diver insignia are qualification badges of the uniformed services of the United States which are awarded to servicemen qualified as divers. Originally, the diver insignia was a cloth patch decoration worn by United States Navy divers in the upper-portion of the enlisted service uniform's left sleeve during the first part of World War II, when the rating insignia was worn on the right sleeve. When enlisted rating insignia were shifted to the left sleeve in late World War II, the patch shifted to the upper right sleeve. The diving patch was created during World War II, and became a breast insignia in the late 1960s.
In the United States Armed Forces, a line officer or officer of the line is a U.S. Navy or U.S. Marine Corps commissioned officer or warrant officer who exercises general command authority and is eligible for operational command positions, as opposed to officers who normally exercise command authority only within a Navy Staff Corps. The term line officer is also used by the U.S. Air Force and U.S. Coast Guard to indicate that an officer is eligible for command of operational, viz., tactical or combat units. The term is not generally used by officers of the U.S. Army – the roughly corresponding Army terms are basic branch and special branch qualified officers, although the concepts are not entirely synonymous, as some Army special branch officers are eligible to hold command outside their branch specialty.
In the United States Armed Forces, the Combat Medic/Healthcare Specialist is responsible for providing emergency medical treatment at a point of wounding in a combat or training environment, as well as primary care, and health protection and evacuation from a point of injury or illness. Additionally, medics may also be responsible for the creation, oversight, and execution of long-term patient care plans in consultation with- or in the absence of a readily available physician or advanced practice provider. Combat medics may be utilized in hospitals and clinics where they have the opportunity to work in additional roles such as operating medical and laboratory equipment, performing and assisting with procedures, and beyond.
The Army Medical Department of the U.S. Army (AMEDD), formerly known as the Army Medical Service (AMS), encompasses the Army's six medical Special Branches. It was established as the "Army Hospital" in July of 1775 to coordinate the medical care required by the Continental Army during the Revolutionary War. The AMEDD is led by the Surgeon General of the U.S. Army, a lieutenant general.
The United States Marine Corps is organized within the Department of the Navy, which is led by the Secretary of the Navy (SECNAV). The most senior Marine commissioned officer is the Commandant of the Marine Corps, responsible for organizing, recruiting, training, and equipping the Marine Corps so that it is ready for operation under the command of the unified combatant commanders. The Marine Corps is organized into four principal subdivisions: Headquarters Marine Corps, the Operating Forces, the Supporting Establishment, and the Marine Forces Reserve.
Military organization or military organisation is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use ad hoc structures, while formal military organization tends to use hierarchical forms.
The Surgeon General of the Air Force is the senior-most Medical Service officer in the United States Department of the Air Force and thus serves as Surgeon General for both the Air Force and United States Space Force. In recent times, this has been a lieutenant general who serves as head of the United States Air Force Medical Service (AFMS). The Surgeon General is usually the senior Medical Corps officer, but acting surgeons general have been from other branches of the medical service.
A medical corps is generally a military branch or officer corps responsible for medical care for serving military personnel. Such officers are typically military physicians.

A logistics officer is a member of an armed force or coast guard responsible for overseeing the support of an army, air force, marine corps, navy or coast guard fleet, both at home and abroad. Logistics officers can be stationary on military bases or deployed as an active part of a field army, air wing, naval force or coast guard fleet. The responsibilities of Logistics Officers vary, depending on where they are deployed and what tasks they are assigned. In addition, different countries have different roles for Logistics Officers.

Service numbers were used by the United States Armed Forces as the primary means of service member identification from 1918 until 1974. Service numbers are public information available under the Freedom of Information Act, unlike social security numbers which are protected by the Privacy Act of 1974.
A squadron in air force, army aviation, or naval aviation is a unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flights, depending on aircraft type and air force. Land based squadrons equipped with heavier type aircraft such as long-range bombers, cargo aircraft, or air refueling tankers have around 12 aircraft as a typical authorization, while most land-based fighter equipped units have an authorized number of 18 to 24 aircraft.
The unification of the Canadian Armed Forces took place on 1 February 1968, when the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force were merged to form the Canadian Armed Forces.
