1st Foreign Engineer Regiment

1er REG insignia1er Régiment Étranger de Génie, 1er REG. One of the two combat engineer regiments of the French Foreign Legion. The 1er REG has been stationed in the Quartier Général Rollet, located at Laudun, Southern France. It provides combat engineering support for Legion units and French Army regular units.

The 1st Foreign Engineer Regiment draws its lineage, attributes, and traditions from the 6th Foreign Infantry Regiment, a unit organized in Syria in 1939 and disbanded in Tunisia in 1955.

The regiment was created in July 1984, as the 6th Foreign Engineer Regiment (6e REG). The 6e REG served in the Central African Republic, Chad, the Gulf War, the former Yugoslavia. In 1999, the 6e REG was redesignated and became the 1er REG. The latter took part in operations in Kosovo, Afghanistan (it was the first Legion unit to be deployed there), Mali, the Central African Republic, and other military operations.

The regiment also operates a platoon of Engineer Combat Divers (PCG, formerly DINOPS) and the Explosive Ordnance Disposal (EOD) team, comprising EOD specialists trained and experienced in dealing with the disarmament and disposal of highly explosive munitions. They are part of the Combat Support Company, which includes other specialists and commando-like elements.
