crossbow used by French and British forces on the Western Front during World War I. It was designed to throw a hand grenade in a high trajectory into enemy trenches. It was initially dismissed by the French Army but General Henri Berthelot thought it had practical value. It was lighter and more portable than the Leach Trench Catapult, but less powerful. The Sauterelle replaced the Leach Catapult in British service until they were replaced in 1916 by the 2 inch Medium Trench Mortar and Stokes mortar.

The Crossbow Launcher is a gadget featured in Battlefield 1 for the Support kit. It was made available in the Giant's Shadow update. As the name suggests, it is a Crossbow that allows players to silently fire different types of grenades at enemies.
Grenades launched from the crossbow explode shortly after hitting the ground, no matter their trajectory.
Two ammo types are available for the crossbow: Frag and High Explosive. They are functionally the same as those available for the Rifle Grenade used by the Medic class. Although the frag grenade inflicts more maximum damage, the HE grenade will explode on impact with a vehicle.
