The legion was heavily engaged in fighting against the National Liberation Front and the Armée de Libération Nationale (ALN). The main activity during the period 1954–1962 was as part of the operations of the 10th Parachute Division and 25th Parachute Division. The 1st Foreign Parachute Regiment, 1er REP, was under the command of the 10th Parachute Division (France), 10ème DP, and the 2nd Foreign Parachute Regiment, 2ème REP, was under the command of the 25th Parachute Division (France), 25ème DP. While both the 1st Foreign Parachute Regiment (1er REP), and the 2nd Foreign Parachute Regiment (2ème REP), were part of the operations of French parachute divisions (10ème DP and 25ème DP established in 1956), the Legion's 1st Foreign Parachute Regiment (1er REP), and the Legion's 2nd Foreign Parachute Regiment (2ème REP), are older than the French divisions. The 1er REP was the former thrice-reconstituted 1st Foreign Parachute Battalion (1er BEP) and the 2ème REP was the former 2nd Foreign Parachute Battalion (2ème BEP). Both battalions were renamed and their Legionnaires transferred from Indochina on 1 August 1954 to Algeria by 1 November 1954. Both traced their origins to the Parachute Company of the 3rd Foreign Infantry Regiment commanded by Legion Lieutenant Jacques Morin attached to the &lt;a href="1st%20Parachute%20Chasseur%20Regiment"&gt;III/1er R.C.P&lt;/a&gt;.
