Engineers developing safer, more accurate tracer round
Tracer rounds ricochet off of a tank as security police fire a mounted .50-caliber machine gun. Tracer rounds enable the shooter to follow the projectile trajectory to make aiming corrections. However, the light emitted by these rounds also gives away the position of the shooter. Engineers at Picatinny Arsenal are part of a joint effort to develop a new type of tracer that reduces the visible signature of tracer rounds.
