The Confederate States Marine Corps (CSMC), also referred to as the Confederate States Marines, was a branch of the Confederate Navy during the American Civil War. It was established by an act of the Provisional Congress of the Confederate States on March 16, 1861. The Corps' manpower was initially authorized at 45 officers and 944 enlisted men, and was increased on September 24, 1862, to 1,026 enlisted men. The organization of the Corps began at Montgomery, Alabama, and was completed at Richmond, Virginia, when the capital of the Confederate States was moved to that location. The headquarters and main training facilities remained in Richmond throughout the war, located at Camp Beall on Drewry's Bluff and at the Gosport Shipyard in Portsmouth, Virginia. The last Marine unit surrendered to the Union army on April 9, 1865, with the Confederacy itself capitulating a month later.

The entire unit of American Marines and Popular Forces militia members together was designated as a Combined Action Platoon (CAP).
A carrier air wing is an operational naval aviation organization composed of several aircraft squadrons and detachments of various types of fixed-wing and rotary-wing aircraft. Organized, equipped and trained to conduct modern US Navy carrier air operations while embarked aboard aircraft carriers, the various squadrons in an air wing have different but complementary missions, and provide most of the striking power and electronic warfare capabilities of a carrier battle group (CVBG). While the CVBG term is still used by other nations, the CVBG in US parlance is now known as a carrier strike group (CSG).

In the United States (US) Department of Defense, a beret flash is a shield-shaped embroidered cloth that is typically 2.25 in (5.72 cm) tall and 1.875 in (4.76 cm) wide with a semi–circular base that is attached to a stiffener backing of a military beret. These flashes—a British English word for a colorful cloth patch attached to military headgear—are worn over the left eye with the excess cloth of the beret shaped, folded, and pulled over the right ear giving it a distinctive appearance. The embroidered designs of the Army's beret flashes represent the heraldic colors and patterns of a unit with a unique mission or represent the history of the Army.

Joint beret flashes—such as those worn by the Multinational Force and Observers and the Joint Communications Support Element—are worn by all who are assigned, given their uniform regulations allow.
