The following year, when the RAF introduced its own rank system, RAF colonels became group captains, reflecting both the level of command responsibility and the seniority of naval captains (the equivalent Royal Navy rank).

Commonwealth nations

In the RAF (like the air forces of most other Commonwealth countries), a group is made up of several stations or wings, each of which typically controls two or more squadrons, so that a group normally includes six to 10 squadrons. When the ranks of the RAF were designed, an officer with the rank of group captain (equivalent to colonel and naval captain) commanded such a unit, although by the time of World War II, many groups were commanded by air commodores (equivalent to brigadiers/brigadier generals and commodores) or air vice-marshals (equivalent to major generals and rear admirals).

US Air Force

(USAF) a group consists of two or more squadrons, often functionally aligned within a wing. Per AFI 38-101 Air Force Organization (21 April 2015) a group is a "level of command between wings and squadrons. Groups bring together multiple squadrons or other lower echelon units to provide a broader capability." Prior to 1991, it was not unusual for a USAF support group to have no subordinate squadrons, but merely be a larger unit than a squadron. In such cases the group would not have a headquarters. USAF groups may be dependent or independent: "A dependent group is a mission, maintenance, mission support, medical, or large functional unit (e.g., security forces, special tactics, communications, etc.) that encompasses a number of related squadrons to provide the specified capability to a parent wing. Such groups may possess small supporting staff elements, such as standardization and evaluation or quality control, that are organized as sections." "An independent group has the same functions and responsibilities as a like-type wing but its scope and size do not warrant wing-level designation and associated overhead costs." A group requires at least 400 personnel, while a wing requires at least 1,000. A fighter wing, for example, is normally composed of dependent groups: an operations group of typically three flying squadrons and an operations support squadron and a maintenance group with aircraft, equipment, and component maintenance squadrons and a maintenance support squadron. Wings responsible for an air base also have other dependent groups such as a mission support group (security, communications, logistics support, mission support, and civil engineering squadrons) and a medical group. The dependent group commanders are considered to be in command billets, but they function like staff officers (the A3/S-3/G-3/J3 or the A4/S-4/G-4/J4) in other organizations. Independent groups are effectively small wings with both flying and maintenance squadrons. USAF groups are usually commanded by officers in the grade of OF-5 (US pay grade O-6), i.e., a full colonel. Wings are also usually commanded by officers in the grade of OF-5, but these are typically more senior colonels by virtue of time in grade and/or date of rank. Some USAF wings are also commanded by officers in the grade of OF-6 (US pay grade O-7), i.e., a brigadier general.

Marine Aircraft Groups consist of two or more aircraft squadrons (usually four to six) and can range to as many as ten (see MAG-14). A MAG also contains a Marine Aviation Logistics Squadrons (MALS) (intermediate aircraft maintenance, aviation supply, and aviation ordnance support), a Marine Wing Support Squadron (MWSS) (air base functions), and a MAG headquarters detachment with a colonel as the commanding officer. The MAG is the organizational equivalent of a Marine Regiment. Marine Air Control Groups (MACG) consist of several aviation command, control, communications, and air defense units. These units include: a Marine Air Control Squadron (MACS) (control of air traffic and tactical air defense), a Marine Air Support Squadron (MASS) (control and coordination of tactical aircraft operations directly supporting ground forces), a Marine Tactical Air Command Squadron (MTACS) (command of tactical ground support and tactical air defense), a Marine Wing Communication Squadron (MWCS) (wire, radio, data, and satellite services), and a Low Altitude Air Defense (LAAD) (ground-based anti-aircraft missile and machinegun weapons) battalion/detachment, under a MACG headquarters detachment, commanded by a

Even today, the commander of the carrier air wing is traditionally called "CAG," a legacy title from when they were known as "commander, air group." A USN aviation wing is designated as either carrier air, maritime patrol & reconnaissance, strategic communications, training air, or type (there are type wings for strike fighters, electronic warfare, airborne early warning and logistics, maritime strike helicopter, and sea combat helicopters that provide squadrons to the carrier air wing for operations, as well as shore based fleet logistics support and tactical support wings that operate independently of aircraft carriers). All of these entities maintain administrative and standardization control and are OF 5 (US pay grade O-6) captain commands roughly analogous to a USMC Marine Aircraft Group or USAF wing.

The commodores of the other USN aviation organizations will also report to similar rank flag officers, e.g., patrol & reconnaissance wing commodores reporting to the commander, Patrol and Reconnaissance Group (COMPATRECONGRU); training air wing commodores reporting to the Chief of Naval Air Training (CNATRA); tactical air control group commodore reporting to an expeditionary strike group (ESG) commander, etc.
