A naval air station (NAS) or navy airbase is a military air base under the command of a navy, dedicated to the use of aircraft for naval operations. These bases are typically populated by squadrons, groups or wings of navalised aircraft, their various support facilities, and other tenant commands.

The term "naval air station" is used by many countries' navies, such as the United States Navy, the Royal Australian Navy, the Royal Navy, and the Indian Navy. In the case of the U.S. Navy, similar facilities in the U.S. Marine Corps are known as Marine Corps Air Stations and facilities in the U.S. Coast Guard are known as Coast Guard Air Stations.

A drill team can be one of four different entities:

1. A military drill team is a marching unit that performs routines based on military foot or exhibition drills. Military drill teams perform either armed or unarmed.
2. A dance drill team creates routines based on precision dance movements rather than military drill. These teams usually do not carry anything, but may use props in field production numbers. They may perform to recorded music, or the live music of an accompanying marching band.
3. A team that execute routines carrying either one or multiple flags or pom-poms. This team's movements are also based in dance and may also have a heavy influence of gymnastics as well. These teams also may perform to music, either live or recorded.
4. A team that is mounted (horse, motorcycle, etc.) or advances some type of mobile object (library carts, lawn chairs, or even garbage bins). May also include teams of dogs and handlers.

The M14 rifle, officially the United States Rifle, Caliber 7.62 mm, M14, is an American battle rifle chambered for the 7.62×51mm NATO cartridge. It became the standard-issue rifle for the U.S. military in 1957, replacing the M1 Garand rifle in service with the U.S. Army by 1958 and the U.S. Marine Corps by 1965; deliveries of service rifles to the U.S. Army began in 1959. The M14 was used by the U.S. Army, Navy, and Marine Corps for Basic and Advanced Individual Training from the mid-1960s to the early 1970s.

The M14 was the last American battle rifle issued in quantity to U.S. military personnel. In 1967, it was officially replaced by the M16 assault rifle, a lighter weapon with a smaller 5.56×45mm intermediate cartridge. The M14 rifle remains in limited service across all branches of the U.S. military, with variants used as sniper and designated marksman rifles, accurized competition weapons, and ceremonial weapons by honor guards, color guards, drill teams, and ceremonial guards. Civilian semi-automatic variants are used for hunting, target shooting, and shooting competitions.
