Yanme'e

The Drones, or Yanme'e by their name, are insectoid biped members of the Covenant. They are often referred to as "buggers". Although they have been part of the Covenant for some time, they have just recently been put to use as combatants. In the Halo 2: Collectors Edition instruction manual it is said they are suited to flight and combat in a gravitational-pull like Earth. This possibly means their home world is like our own.

Drones are insectoid and are covered in natural chitinous armor, although it doesn't provide that much protection. If you look carefully at a dead Drone you can see small round technological/metal objects on its armor, it is assumed by some that these are small shield generators employed to make up for the Drones' obvious weakness. It seems like the drones share a ranking system in colored armor, but it is unclear who is leader. After the Covenant Civil War began, the Drones took the side of the Brutes.

Combat
Drones prefer to stay at a distance and use long range tactics. However, they are skilled close-range combatants as well if the need arises. They always appear in swarms, and usually in large, open areas, where, combined with their agility, they are hard to target effectively. Drones also have the distinction of being able to board vehicles. However they do not seem capable of driving them, but will beat mercilessly until the driver is either tired of this, or is killed. The only reason why they were used was because the Marines were never trained to deal with "aerial infantry".

They wield lightweight weapons such as the Needler and Plasma Pistol.They never charge up a shot of their Plasma Pistol to break a shield. They also enter battle in a pack (the number differs depending on the difficulty). Furthermore, they are not susceptible to headshots, though sniper weapons will always kill them with a single shot regardless of where it hits them. This is most likely due to a natural physical weakness. Drones never dual wield or have heavy weapons because they can only become airbourne while lifting a small amount of weight.
