Attached to the 2nd Foreign Infantry Regiment, the company depended on the battalions implanted in Central Vietnam.

After the 1st battalion, the disciplinary mission was transferred to the 4th, which arrived in February 1950, being found in Quảng Nam Province.

The disciplinary company handled the disciplining of all Foreign Regiments present in French Indochina.

The CDRE/EO was dissolved on August 1, 1954, while Tagne Island was placed at the disposal of French Navy Commando Jaubert.

The grenade with 7 flames is the symbol of the Legion; the white sail is that of a Junk ship, which referred to the unit's location on an island, accessible to land only by boat; the inscription means : "The Law is harsh, but it is the Law," evoking the character of the unit.
