ERYX is a short-range portable SACLOS-based wire-guided anti-tank missile (ATGM) produced by European company MBDA. It is used by several countries, including the Canadian Army, French, and Norwegian armies. The weapon can also be used against bunkers and pillboxes. It also has some capability in the anti aircraft role to bring down low flying helicopters, due to its wire guided system. An agreement was reached in 1989 between the French and Canadian governments to co-produce the ERYX missile system. It entered service in 1994.
