FN created what is possibly the classic post-war battle rifle. Formally introduced by its designers Dieudonne Saive and Ernest Vervier in 1951, and produced two years later, it has been described as the "right arm of the Free World." The FAL battle rifle has its Warsaw Pact counterpart in the AK-47, each being fielded by dozens of countries and produced in many of them. A few, such as Israel and South Africa, manufactured and issued both designs at various times. Unlike the Russian AK-47 assault rifle, the FAL utilized a heavier full-power rifle cartridge. In the West, FAL's primary competitor was the German Heckler & Koch G3.
