Sailor Riflemen

Battalions and companies of sailors are dedicated to the protection of sensitive naval sites. The sailors are also an integral part of buildings as domestic service - called "bidellerie" in navy slang.
There are seven companies of sailors, which provide protection for the following sites:

Military port of Cherbourg
Submarine base in Île Longue and pyrotechnics in Guenvénez
Naval aviation base in Lann Bihoué
Communications center in Rosnay, Indre
Communications center in Sainte-Assise, Seine-et-Marne
Communications center in Villepinte France and South Saissac, Aude
Naval aviation base in Lanvéoc-Poulmic
Sailor riflemen and Commando training center Lorient

These seven companies send detachments who take turns every four to six months to ensure the protection of the communications centers of Fort-de-France, Mahina Mahina Super and around Papeete, of Ouen Toro in Noumea, and Rufisque near Dakar.
They also support operations of the Navy Commandos, augment boarding parties and provide military training to the French navy.

Navy Commandos

The Commandos Marine are trained to targeted actions in places where it is not feasible or appropriate to deploy a larger force. They are primarily used by the French Special Operations Command since 1992. They are seven in number: Commando Jaubert, Commando Ponchardier, Commando Trepel, Commando de Montfort, Commando de Penfentenyo, Commando Kieffer, and Commando Hubert, each with their own mission specialism. They have evolved to be broadly comparable to the British SBS.
