Enacted on June 4, 1918 by the merger of three Light Tank Battalions each formed of three artillery groups.

In August 1918, making way back to Soissons, the regiment participated within the cadre and corps of the 10e Armée to the counter-attack of Mangin.

While clearing Soissons, the three battalions adopted Vauxaillon as a marching axe and pushed back towards Chemin des Dames.

During the Algerian War, from 1956 to 1963, the regiment was transformed into a training centre prior their departure to Algeria.

Engagements included relieving missions in ex-Yugoslavia, and Kosovo and on all exterior theatres of intervention (Tchad, Lebanon, Kuwait, Central African Republic, as well as Senegal, the Ivory Coast and Afghanistan).

In 1939, six companies were entitled to wear the fourragere with colors of the Croix de Guerre 1914-18 and the Médaille militaire.

In 1918, these companies were combined to form the 501e RCC which authorizes that regiment to wear the fourragere with colors of the Médaille militaire.
