The forts primary function was to provide fire support using its; two 75mm guns, 81mm mortar and 135mm gun. The fort also had a number of machine gun cloches that were fitted with 7.5mm MAC 31 machine guns. Bréhain faced no direct assault during World War Two but did engage German forces on a number of occasions. Between September 1939 and June 1940, Bréhain fired 20,250 75mm shells, 1,780 81mm mortars and 2,220 135mm shells. Bréhain surrendered on the 27 June 1940.

When the French nuclear deterrent became operational, the fortifications were stood down. Bréhain remains the property of the French Army.
