Lance-grenade individuel Mle F1 (LGI Mle F1)

The LGI Mle F1 is a French close-support weapon infantry weapon designed to be used by one man, which provides soldiers with a lightweight indirect-fire support weapon similar to a small mortar. And in many ways, it fulfills the same sort of roles as the Type 89 grenade discharger used by the Japanese Army during World War II. The LGI has been used by the Foreign Legion and other French Army forces since the 1990s.[2]

French squads are divided into a 300-metre fireteam each armed with a FAMAS 5.56 mm assault rifle and carrying an AT4 anti-tank weapon and a 600-metre fire-team with a FN Minimi another FAMAS and a LGI.

The mortar uses bombs with a method of propulsion called FLY-K, a closed combustion chamber to capture all the propulsion gases. The propellant charge is inserted into the stabilizing tail of each projectile so the weapon transmits the ignition impulse to the grenade via an enclosed internal system. This concept assures little in the way of noise, muzzle flash, smoke and without a significant thermal signature. The noise made on firing is only 52 dB, making it hard to detect the launching point and high rates of sustained fire are possible as the weapon does not heat up.[3]

The LGI can fire anti-personnel, anti-materiel, blinding, smoke and illumination rounds.
