Halo 2-3 Drone Enemy

First off, this is my fiftieth post. Second, The "drone" is an insect-like enemy in halo 2 and 3. I have never actually fought one, but I've heard a lot about them. They are very weak, but travel in large swarms. Drones usually carry a plasma pistol, because it is the only thing light enough for them to fly with. I am not sure, but i think they can use needlers as well. Drones are very hard to hit with sticky grenades and are almost always hovering out of reach of normal (non-sticky) grenades. Using a stationary gun against drones is not a good idea because they will tear you apart with plasma pistol fire very fast if you stand still. The best way to fight drones is to keep moving and fire in controlled bursts.
