The United States has eight federal uniformed services that commission officers as defined by Title 10 and subsequently structured and organized by Titles 10, 14, 32, 33, and 42 of the U.S. Code.
Military police (MP) are law enforcement agencies connected with, or part of, the military of a state. In wartime operations, the military police may support the main fighting force with force protection, convoy security, screening, rear reconnaissance, logistic traffic management, counterinsurgency, and detainee handling.
United States astronaut badges are the various badges of the United States which are awarded to military and civilian personnel who are employed with the National Aeronautics and Space Administration, who have performed a spaceflight. The military versions are among the least-awarded qualification badges of the United States armed forces.
The Air and Space Training Ribbon (ASTR) is the lowest military award of the United States Air Force and United States Space Force, ranking only above foreign military awards.
Security police usually describes a law enforcement agency which focuses primarily on providing security and law enforcement services to particular areas or specific properties. They may be employed by governmental, public, or private institutions. Security police are generally considered distinct from security guards as security police personnel typically hold some level of law enforcement authority. The exact powers held by security police vary widely between jurisdictions. Examples of these types of agencies include the United States' DoD Police and FBI Police, the Indian Central Industrial Security Force, and the British Civil Nuclear Constabulary.
Identification badges of the uniformed services of the United States are insignia worn by service members conducting special duties, many of which can be awarded as permanent decorations if those duties are performed successfully. There are a few identification badges that are awarded to all services, others are specific to a uniform service. The Office of the President and Vice President and department/service headquarters badges are permanent decorations for those who successfully serve in those assignments. Some of the service level identification badges can be permanent decorations and others are only worn by a service member while performing specific duties, such as the Military Police Badge.
Badges of the United States Air Force are specific uniform insignia authorized by the United States Air Force that signify aeronautical ratings, special skills, career field qualifications, and serve as identification devices for personnel occupying certain assignments.
The United States Air Force Security Forces (SF) are the ground combat force and military police service of the U.S. Air Force and U.S. Space Force. The USAF Security Forces were formerly known as Military Police (MP), Air Police (AP), and Security Police (SP) at various points in their history. Due to its significant ground combat mission, Security Forces are sometimes regarded as Air Force infantry. They were formed on the premise of being the Air Force's "Marine Corps", in that they would provide security for the Air Force similar to how the Marines provide security for the Navy.
A physical training uniform is a military or organizational uniform used during exercise, calisthenics, drills, and in some cases, very casual periods of time. Most militaries, especially the United States Armed Forces and their auxiliaries require use of a physical training (PT) uniform during unit exercise. All items worn by military personnel conducting PT as a group are subject to uniformity, at commander discretions, however, some U.S. military units produce unique T-shirts with their unit insignia and motto, and for special events, this shirt is part of the uniform. Occasionally, exercise will also be conducted in that branch's utility uniforms, normally with the blouse removed and the undershirt exposed. For unit runs, esprit de corps or special occasions, commanders may have personnel wear unique T-shirts with the distinctive unit insignia and unit colors.
Provosts are military police (MP) whose duties are policing solely within the armed forces of a country, as opposed to gendarmerie duties in the civilian population. However, many countries use their gendarmerie for provost duties.
The uniforms of the United States Air Force are the standardized military uniforms worn by members of the United States Air Force to distinguish themselves from the other services.
The federal government of the United States empowers a wide range of federal law enforcement agencies to maintain law and public order related to matters affecting the country as a whole.
United States Department of Defense police are the uniformed civilian security police officers of the United States Department of Defense (DoD), various branches of the United States Armed Forces, or DoD agencies.
Troops began wearing berets as a part of the headgear of military uniforms in some European countries during the 19th century; since the mid-20th century, they have become a component of the uniforms of many armed forces throughout the world. Military berets are usually pushed to the right to free the shoulder that bears the rifle on most soldiers, but the armies of some countries, mostly within Europe, South America, and Asia, have influenced the push to the left.
The Department of the Army Civilian Police (DACP), also known as the Department of the Army Police, is the uniformed, civilian-staffed security police program of the United States Army. It provides professional, civilian, federal police officers to serve and protect U.S. Army personnel, properties, and installations. DACP personnel represent the Department of the Army's contribution to the Department of Defense Police program. DACP law enforcement officers primarily work alongside the U.S. Army Military Police Corps, the Army service members who hold law enforcement military occupational specialities. DACP officers are supplemented by Department of the Army Security Guards, who are uniformed and armed federal security officers, primarily responsible for entry control and basic security tasks. Although the Army Criminal Investigation Division employs civilian special agents, it does not fall-under the DACP nor DoD Police umbrella.
United States Army Counterintelligence (ACI) is the component of United States Army Military Intelligence which conducts counterintelligence activities to detect, identify, assess, counter, exploit and/or neutralize adversarial, foreign intelligence services, international terrorist organizations, and insider threats to the United States Army and U.S. Department of Defense (DoD).
Captain in the U.S. Army (USA), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system and is different from the higher Navy/Coast Guard rank of captain. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version.
The United States Coast Guard Police (CGPD) are law enforcement units stationed at certain shore facilities of the United States Coast Guard.
The Master-at-Arms (MA) rating is responsible for law enforcement and force protection in the United States Navy—equivalent to the United States Army Military Police, the United States Marine Corps Military Police, the United States Air Force Security Forces, and the United States Coast Guard's Maritime Law Enforcement Specialist. It is one of the oldest ratings in the United States Navy, having been recognized since the inception of the U.S. Navy.
Badges of the United States Space Force are specific uniform paraphernalia authorized by the United States Space Force that signify ratings, special skills, career field qualifications, and serve as identification devices for personnel occupying certain assignments. Space Force occupational badges are awarded in three degrees or skill levels. Badges for space operations are awarded at basic, senior, and command levels; other occupational badges are issued in basic, senior, and master level. A star and wreath system, worn above the badge, denotes which degree or skill level a service member currently holds.
