In 1974, renowned Belgian arms company Fabrique Nationale brought out a ground-breaking new light machine gun, the Minimi. Its success has been meteoric, arming more than 45 countries around the world. The Minimi offers the ultimate in portable firepower. Firing the high-velocity 5.56x45mm round, the Minimi is a gas-operated, lightweight, belt- or magazine-fed weapon, able to burn through cartridges at a cyclical rate of up to 1,150 rounds per minute, making it the weapon of choice for fire support at squad level. This study uses gripping first-hand accounts and striking combat photographs, following the Minimi to war zones such as Iraq and Afghanistan. It tracks its design and development, as well as investigating what has made it so compelling a choice for armed forces around the world for more than 40 years.
