They are the first choice units for overseas deployment and recruit on this basis. They are composed of Marine Infantry ("Infanterie de Marine") (which includes parachute regiments such as 1er RPIMa and a tank unit, the RICM) and the Marine Artillery ("Artillerie de Marine"). The "Aviation légère de l'Armée de terre" (ALAT, which translates as Army Light Aviation), was established on 22 November 1954 for observation, reconnaissance, assault and supply duties. It operates numerous helicopters in support of the French Army, its primary attack helicopter is the Eurocopter Tiger, of which 80 were ordered. It is an "Arme" with a "commandement particulier". On the administrative side, there are now no more than one Direction and two services. The Army Human Resources Directorate (DRHAT) manages human resources (military and civilian) of the Army and training. The two Services are the service of ground equipment, and the integrated structure of operational maintenance of terrestrial materials (SIMMT, former DCMAT). This joint oriented service is responsible for project management support for all land equipment of the French army. The holding-operational equipment the Army is headed by the Service de maintenance industrielle terrestre (SMITer). Historically there were other services of the Army who were all grouped together with their counterparts in other components to form joint agencies serving the entire French Armed Forces. After the health service and the service of species replaced respectively by the French Defence Health service and Military Fuel Service, other services have disappeared in recent years:   The Army Commissariat was dissolved on 31 December 2009 and intégrated into the joint-service Service du commissariat des armées. There is the Diocese of the French Armed Forces which provides pastoral care to Catholic members of the Army. It is headed by Luc Ravel and is headquartered in Les Invalides. For many years up to 19 military regions were active (see ). The 10th Military Region (France) supervised French Algeria during the Algerian War. However, by the 1980s the number had been reduced to six: the 1st Military Region (France) with its headquarters in Paris, the 2nd Military Region (France) at Lille, the 3rd Military Region (France) at Rennes, the 4th Military Region (France) at Bordeaux, the 5th at Lyons and 6th at Metz. Each supervised up to five "division militaire territoriale" – military administrative sub-divisions, in 1984 sometimes supervising up to three reserve regiments each.
