US soldiers deployed in Syria are testing a new electronic rifle scope that won't allow a shot to be fired until an onboard targeting system can guarantee it will hit its target. Called SMASH 2000, the scopes use a Linux-based imaging system to calculate the most accurate bullet trajectory to a specific target, which soldiers first'mark' by aiming the scope and pressing a small button near the rifle grip. When the soldier is ready to fire, the system determines if their aim is true, and if the soldier's aim is off, the system won't allow the gun to fire even if the trigger is pulled. US troops in Syria are testing a new scope, called SMASH 2000, that won't allow soldier's to fire unless the targeting system believes the shot will hit its target In field testing at the US Army's al-Tanf base in Syria, near the country's southeastern borders with Jordan and Iraq, soldiers have used the SMASH 2000 scope to target small drone-mounted boxes as they move across the sky. The scopes have previously been used in the field by the Israel Defense Force, but according to manufacturer Smart Shooter Ltd., this marks the first time they've been used in Syria.
