The Carabinieri Regiment is popular for their famous horse carousel that reaches reenacts the Carabinieri's charge at the Battle of Pastrengo. History 
While mounted units of the Carabinieri existed since their inception, the 4th Carabinieri Mounted Regiment traces its origins to the formation of the 11th Carabinieri Mechanized Brigade. The brigade was established to  adjust the organization of the Battalions and of cavalry units for both military and public order tasks. The aim was to ensure Carabinieri Battalions the availability of all elements necessary to be in a position to act in isolation and overcome considerable resistance without having to rely on the competition of other Army Corps or other Armed Forces, to ensure Battalions speed of movement and concentration in large sectors of foreseeable use and a constant high training level. The 4th Cavalry Carabinieri Regiment (based from the beginning in Rome) was subordinated to the Brigade Command and consisted of 2 Squadrons Groups (Battalion-level units) and 1 Armoured-motorized Squadron:
 Command Squadron (company-level unit);
 Armoured-motorized Squadron;
 I Squadrons Groups "Pastrengo";
 II Squadrons Groups "Allievi";
 Equestrian Centre. On 15 June 1965, the regiment organization was heavily modified: the II Squadrons Group "Allievi" passed under Students Legion in Rome, while three Territorial Squadrons Group in Milan, Cagliari and Palermo passed under the Regiment with the name of II, III and IV Squadrons Group. On 1 January 1966, the Regiment lost the Equestrian Centre. In 1967, the Regiment was given the Equestrian Sport Sections Detachment in Montelibretti. On 31 October 1968, the Armoured-Motorized Squadron and the Squadrons Groups of Milan, Cagliari and Palermo were disestablished, leaving the Regiment with 1 Command Squadron and 1 Squadrons Group; the following day the II Squadrons Group was established. The Equestrian Sport Sections Detachment was disestablished and on 16 November 1968 the Regiment gained two Carabinieri Detachments Equestrian Sections in Montelibretti and in Castro Pretorio. In 1972 the Command Squadron was transformed in Command Unit, under the leadership of a Major or a Lieutenant Colonel and the post of Officer assigned to the Command was abolished. In 1974 the two Carabinieri Detachments Equestrian Sections were disbanded. In 1976 the Regiment regained the Equestrian Centre, and the following year the unit was renamed as the Carabinieri Cavalry Regiment. In 2001 the Regiment was assigned to the newly formed 1st Carabinieri Mobile Brigade and in 2007 it regained the original name "4th Carabinieri Cavalry Regiment". In 2009 the Equestrian Sports Section was separated from the Regiment. A further regimental reorganisation took place in 2012. Organization
