The proportion of Maghrebis reached 69% for the regiment, 74% for the battalion, 79% for the company of fusiliers-voltigeurs, 52% for the anti-tank company and 36% for the cannon infantry company.[3]

The 7e RTA fought in the Algerian War, in the corps of the 21st Infantry Division, in the sector of Aurès Nemencha. At the cease-fire on 19 March 1962, the regiment constituted along with 91 other regiments, a local unit force of the Algerian order of battle, the 427 UFL-UFO composed of 10% of metropolitan military and 90% of Muslim military personnel at Barika, during the transition period, while being at the service of the executive provisionary power of Algeria until the independence of Algeria (Evian Accords, 18 March 1962).
Following that, the regiment was back in France in 1962, and garrisoned until 1964, when the unit was dissolved to form the 170th Infantry Regiment.
