Structure of the Argentine Army

The Structure of the Argentine Army is made up of administrative branches and the field organisation of three divisions and the parachute brigade which is part of the Rapid Deployment Force.

The current active force of the Argentine Army includes a total of ten brigades (brigadas). There are:
 * 2x Armored brigades (1st, 2nd)
 * 1x parachute brigade, the 4th Parachute Brigade (Argentina)
 * 3x Mountain infantry brigades (5th, 6th, 8th) (Note: 5th Brig. is equipped like a Mechanized Brigade)
 * 3x Mechanized brigades (9th, 10th, 11th)
 * the 12th Jungle Brigade (Argentina)

In addition to the brigades, there is also a number of specialized formations, amongst them:
 * the 601st Anti-aircraft Artillery Group.
 * An Argentine Army Aviation group, which administers and operates almost all of the Army's aircraft except for those detached to the brigade level.
 * The Buenos Aires Military Garrison, which serves for ceremonial purposes.
 * the Special Operations Forces Group

The "regiment" and "group" designators actually denote battalion-sized units ("regiment" being used for infantry and cavalry units and "group" used for artillery units).

1990s reorganization
Since the restoration of democracy in 1983, the Argentine Army were reduced both in number and budget but became more professional, especially after conscription was abolished. Some units were dissolved and other moved, e.g.,
 * I Corps (Buenos Aires) dissolved
 * 10th Infantry Brigade (Buenos Aires) moved to La Pampa
 * In accordance to the friendship policy toward Brazil
 * 7th Jungle Infantry Brigade, dissolved
 * 3rd Motorized Brigade, dissolved
