Droid attack flare

A droid attack flare, also known as an alert flare, was a flare used by the forces of the Galactic Republic during the Clone Wars against the Confederacy of Independent Systems. A droid attack flare could be fired to alert allied forces of danger. Shortly after the attack on the Republic's Rishi Moon base by Separatist commando droids in 22 BBY, the surviving clones alerted the recently arrived Clone Captain Rex and Clone Commander Cody to the threat of battle droids using the droid attack flare.
