How the Predator UAV Works Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1Predator Unmanned Aerial Vehicle. These high-tech aircraft‚ controlled by a crew miles away from the dangers of combat‚ are capable of reconnaissance‚ combat and support roles in the hairiest of battles. In a worst-case scenario‚ if a Predator
