Last month, the Warrior-Alpha unmanned aircraft fired its first missiles at actual, live targets in battle. In the Diyala Province on February 23rd, the drone fired missiles at insurgents that were battling coalition forces. According to an Army press release, Staff Sgt. Jerry Rhoades said “We neutralized both targets – [the ground forces] were satisfied.”
Even though the Warrior-Alpha has been around and in use since 2007, it's been mostly for surveilance up to this point. This is the fist opportunity the Army has had to, as Tony Stark would say, "let it off the chain."
