2nd Foreign Engineer Regiment

2e REG insignia2e Régiment Étranger de Génie, 2e REG. The newest regiment of the French Foreign Legion, nicknamed the “Mountain Regiment.” Since its activation in 1999, it has been stationed in the Quartier Maréchal Koenig near Saint Christol, at the former site of the French strategic nuclear missiles in southeastern France.

The regiment was created on July 1, 1999 as a combat engineering unit (see 2e REG: The origins). It is assigned to the 27th Mountain Infantry Brigade. The regiment draws its lineage from Legion engineering units serving during the First Indochina War (1946-54).

The 2e REG has already participated in several operations and missions, including those in ex-Yugoslavia, Ivory Coast, Martinique, Afghanistan, Mali, and Niger.

Two GCM groups and a PCG team are assigned to the Surveillance & Direct Action Platoon (SRIO) of the 2e REG. Also within the regiment is an Explosive Ordnance Disposal (EOD) team composed of EOD specialists trained to deal with the disarmament and disposal of highly explosive munitions.
