Army One is the callsign of any United States Army aircraft carrying the president of the United States. An Army aircraft carrying the vice president is designated Army Two.
From 1957 until 1976, the callsign was usually used for an Army helicopter transporting the president. Prior to 1976, responsibility for helicopter transportation of the president was divided between the Army and the U.S. Marine Corps, under the call sign Marine One, until the Marine Corps was given the sole responsibility of transporting the president by helicopter.
The best known helicopters that used the Army One callsign were Sea King VH-3A helicopters that were part of the presidential fleet from 1961 to 1976. During its presidential service, the helicopter was known either as Army One or Marine One, depending on whether Army or Marine pilots were operating the craft. [2] The helicopter, with seats for sixteen, has a seat reserved for the president and the first lady, and single, smaller seats for the two Secret Service agents who always flew with the presidential party.

The Sikorsky CH-37 Mojave is an American large heavy-lift military helicopter of the 1950s. It entered service as the HR2S-1 Deuce with USMC in 1956, and as the H-37A Mojave with the U.S. Army that same year. In the early 1960s the designation was standardized to CH-37 for both services, with the HR2S-1 redesignated as CH-37C specifically.
The Sikorsky CH-53E Super Stallion is a heavy lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. Developed in the 1970s, it entered service in 1981, and is planned to be in service into the 2030s.

Marine Helicopter Squadron One (HMX-1) is a United States Marine Corps helicopter squadron responsible for the transportation of the president and vice president of the United States, heads of state, Department of Defense officials, and other VIPs as directed by the Marine Corps and White House Military Office. A Marine helicopter with the president aboard uses the call sign "Marine One". Previously, HMX-1 was also tasked with operational test and evaluation (OT&E). This task was reassigned to VMX-1 in Yuma, Arizona; since the contract award of the new presidential helicopter in 2014 to Sikorsky Aircraft, however, HMX-1 has assumed the temporary role of OT&E for this platform, because of its unique nature and mission. The VH-92A first flew in 2017 and is expected to be operational sometime after 2022. Nicknamed "Nighthawks", HMX-1 is headquartered at Marine Corps Air Facility Quantico, Virginia, and maintains detachments at Joint Base Anacostia–Bolling in Washington, D.C., and Joint Base Andrews Naval Air Facility in Maryland.
Air assault is the movement of ground-based military forces by vertical take-off and landing (VTOL) aircraft, such as helicopters, to seize and hold key terrain that has not been fully secured, and to directly engage enemy forces behind enemy lines. In addition to regular infantry training, air-assault units usually receive training in rappelling, fast-roping techniques, and air transportation. Their equipment is sometimes designed or field-modified to allow better transportation and/or carrying within aircraft.

Military call signs are call signs or specialized form of nickname assigned as unique identifiers to military communications. In wartime, monitoring an adversary's communications can be a valuable form of intelligence. Consistent call signs can aid in this monitoring, so in wartime, military units often employ tactical call signs and sometimes change them at regular intervals. In peacetime, some military stations will use fixed call signs in the international series.
