Star Wars 2009 Clone Wars Legacy Collection Exclusive Vehicle Stap with Battle Droid

Battle droids use Single Trooper Aerial Platform (STAP) vehicles to patrol a sizable amount of ground in a concise time period. If a droid happens upon Republic forces, he can use the STAP's blaster cannons, but his primary purpose isn't to engage the enemy but rather to look for trouble and, if he finds any, call in reinforcements. It's not without risk, since droids are completely exposed on STAPs, leaving them vulnerable to attack.
