France and Belgium have long shared military ties due to cultural similarities and strategic impact. The two countries signed the Franco-Belgian Military Accord of 1920, but Belgium backed out in 1936 as they wished to remain neutral. However after the 2nd World War both nations were founding members of NATO.
France currently fields several Belgian made weapons including the P90 and SCAR, but the latest addition is Fabrique Nationale Herstal’s EVOLYS. The FN EVOLYS is expected to be in the hands of French special operations forces by this May. FN touts the weapon as one that fires like a machine gun but handles like a rifle.
