Backblast area for FGM-148 Javelin

The backblast area is a cone-shaped area behind a rocket launcher, rocket-assisted takeoff unit or recoilless rifle, where hot gases are expelled when the rocket or rifle is discharged.[1] The backblast area is dangerous to ground personnel,[2] who may be burned by the gases or exposed to overpressure caused by the explosion.[3] In confined spaces, common in urban warfare, even the operators themselves may be at risk. Soft launch methods diminish the backblast.
