Yanme'e

The Yanme ' e (Latin Turpis rex, translated to "dishonourable king" ), also referred to by Humans as Drones, are a race of aerial, intelligent, insectoid warriors which make up part of the unified conglomerate races of the Covenant.

They are informally referred to by UNSC infantry as "buggers" or "Drones". Although they have been part of the Covenant for some time, they have just recently been put to use as combatants in the war against the Humans. Their mastery of antigravity flight assistance has give them an almost insurmountable strategic advantage in combat. They usually travel in swarms of about 12 to 50.

Background
The Yanme'e are human sized, insectoid creatures that are covered in natural chitinous body armor, which affords them rather limited protection against modern weaponry. Yamme'e typically mount small antigravity devices on their exoskeleton to assist in flight. It seems, like the other Covenant species, Yanme'e share a ranking system in colored armor but it is unclear who is the leader in a swarm. They do not interact with other species except to trade and serve in a military capacity and their exact position in the Covenant Hierarchy is relatively unknown, although it is reasonable to believe that they are higher in rank than Grunts and Jackals, but lower rank than Elites and Brutes. They are usually used as mechanical crews on ships when Engineers are not available, though they aren't as effective as the Engineers. In jealousy, they even killed an Engineer named Lighter Than Some. After the Covenant Civil War began, almost all of the Yanme'e took the side of the Covenant Loyalists. The Yanme'e replace Jackal Rangers, as they are much more suited to fly.

The Yanme'e are a eusocial species; meaning their society usually consists of a single reproductive queen, reproductive males and non-reproductive workers and/or soldiers. Because of this, they can be extremely dogmatic and hive minded ; something that may have made for an easy conversion into the Covenant hierarchy. They were one of the newest races to join the Covenant. They are respected by the other Covenant for their natural intelligence, obedience, and technological skill. Their skills with technology have brought them into an often violent rivalry with the Huragok, as seen in Halo: Contact Harvest. While they have been in the Covenant for hundreds of years, for unknown reasons, they were not intentionally used in any major Covenant campaigns until the First Battle of Earth. The Yanme'e fought for the Covenant Loyalists during the Covenant Civil War. Some may possibly have joined the Separatists after the Civil War, although it is unknown if any actually did.

The Yanme'e, much like the Grunts and Hunters, are a conquered race that was forced into service by the Covenant. They strictly follow the Covenant religion and obey any command without question, yet do not partake in social norms due to communication difficulties with other species. They view the Prophets as "Queens", a remnant of their former hive lifestyle. The Queens of the Drones have been described as "enormous" and had to be supported by multiple wingless Drone males. The Drones' language is a cacophony of high-pitched clicking from the rubbing of their waxy, leaf like wings. They are also capable of making loud screeching "vocalizations" that is likely produced by their respiratory system or some other sound making organ.

Evolution
The Yanme'e homeworld is Palamok, a planet much like Earth but twice the size with over twice the gravity(2.2G). It seems extremely unlikely that a flying pseudo-insectoid species could evolve on such a world, since they would likely be incapable of flying even in Earth's gravity (due to their heavy exoskeleton) if it were not for their antigravity generators. Some have proposed that their exoskeletons are hollow, with a lattice work of struts similar to the bones of birds. This is certainly likely, and would be a needed adaptation for such a large creature to fly in Earth's gravity (as well as to simply keep from collapsing under its weight) but it would simply not be enough to fly in 2.2Gs. Of course their antigravity technology would allow them to exist on Palamok, but this still begs to question as to how they evolved in the first place.

One of the most likely answers to the problem of Yanme'e evolution may be found on one of Palamok's four moons; Naxook, Oquiu, Ka'amoti and Kami. Palamok is large enough to support an approximately Mars sized moon with roughly half the gravity of Earth. This would certainly be the ideal location for a large flying insectoid species to evolve. It's possible that they evolved sentience and and eventually space flight and antigravity technology on one of these four moons. The development of small antigravity generators would have allowed them to colonize Palamok in much the same way as spacesuits would allow humans to colonize Mars. Since Palamok is a very large world, it would likely support more Yanme'e then their actual world of origin.

Yanme'e Anatomy and Physiology
The Yanme'e are not true insects, as they do not share a common ancestry (as far as we know) with Terran life. Their resemblance to Earth's insects is probably due to a remarkable degree of convergent evolution. The Yanme'e have segmented bodies supported by an exoskeleton, a hard outer covering made of what may be mostly chitin. It is not known for sure if the Yanme'e exoskeleton consists of true chitin, but considering its abundance in unrelated species on Earth it's certainly possible. In reality, pure chitin is actually leathery rather hard, and arthropods with hard exoskeletons combine calcium and chitin to make for a harder support structure.

Unlike insects, which have three body sections, or tagmata, the segments of the Yanme'e body are broken into five: a head, a cephalothorax, a thorax, a pelvis and an abdomen. The head supports a pair of sensory antennae and a pair of compound eyes. The mouth consists of sets of mandibles like those found on insects. The cephalothorax, or "neck", most likely houses what must be an enlarged brain. The thorax has a pair of segmented arms with razor sharp claws, and two pairs of wings; complete with beetle like wing covers. The first pair of legs are attached to a pelvis like structure, while the second pair is attached to the abdomen. The last set of limbs may help the Yanme'e latch onto surfaces, but otherwise appear vestigial.

Yanme'e exoskeletons are covered with multiple bumps, grooves, indentations and markings. Many of the markings may have evolved as camouflage. On close inspection these markings bear resemblance to a head. This is reminiscent of many Earth insect species that bear markings that confuse predators into attacking less vital parts of their anatomy.

Very little is known about Yanme'e internal anatomy, but we can make some educated inferences based on what has been witnessed in combat. Yanme'e blood appears a mix of green and grey substances which implies they may have an open circulatory system like insects. The Yanme'e are too large to rely entirely on the same type of trachea system found in insects; instead they may have some form of true lung system that delivers oxygen directly to the hemolymph, which in turn may carry copper containing hemocyannins (or something similar) instead of hemoglobin.

There seem to be several different varieties - a copper-colored type, and two green varieties. Though physical details of the copper type are unknown, the first of the green varieties differs from the other in a different mandible structure, feathery antennae, and a lighter coloration. The second green type has a more insectile mandible structure, more simple antennae, and a darker coloration. Whether these traits are indicative of different tasks or functions, or simply a result of genetic variation, is unknown.

Social Behavior and Caste Structure
As mentioned before, the Yanme'e are a eusocial species. They live in colonies built around a single reproductive queen, wingless males, workers and soldiers. The following section will use the correct scientific terminology for eusocial insect castes, rather than the more common UNSC slang names given to this species.

The queen is the central figure of the hive. Her primary role, as with ants and bees, is to propagate the species. Being a sentient species, the queen likely serves as an absolute matriarchal leader; making her a queen in the literal sense as well. The queen has been described as being large with the distended, egg producing abdomen seen in queen termites. This extra bulk would likely limit the queen's mobility. It has been observed that her weight is supported by at least six wingless male drones.
 * Queen

These are drones in the true sense of the word: meaning they are the reproductive male caste like drone bees. The term drone is often incorrectly used for the worker caste of many eusocial species. Little is known about their appearance other than that they are wingless. To prevent inbreeding, the drones would have to come from an unrelated hive. It's likely that they have wings earlier in their lives so they can travel, but they are later lost or removed after mating with the queen. This behavior can be seen in ants and termites. Like the males of eusocial insects, they probably lack any natural weaponry and have enlarged eyes. The males probably exist entirely to fertilize the queen, as well as care for her and move her from place to place. The lack of wings may also render them "mute" as it seems the Yanme'e use their wings to communicate.
 * Drones (Males)

As with many species of ants, there may not be a true division in worker and soldier caste, but the two may simply be different sizes of worker. Within the worker/soldier caste, there appears to be minors (workers) and majors (soldiers). Minors are the most common form and have a very low (as low or lower than the grunts) position in Covenant society. Majors could represent a separate soldier caste: they have larger wings, fly faster, are more skilled in combat and often carry Needlers.
 * Workers and Soldiers

Reproduction and Life Cycle
Almost nothing is known about the Yanme'e life cycle beyond the fact that the queen lays eggs. It's possible that the Yanme'e go through a complete metamorphosis including a egg, larva, pupae and adult stage, but it's equally possible they do not.

Intelligence
Drones probably operate under a collective hive mind, but there is little known about individual drone intelligence and emotional capability. They are able to feel jealousy (as seen when they killed Engineer Lighter Than Some because he usurped their role as technician on Rapid Conversion). In the level Crow's Nest, Thel 'Vadam can be seen trying to convince individual Drones (while fighting them) to reject the Prophets' lies and rebel. However, the Halo 3 Campaign Scoring description of Drone Majors states that Drones are incapable of feeling fear.

Capabilities
Yanme'e are deployed in battle situations, such as aerial insertions, among the Covenant, and during the Covenant Civil War, the Covenant Loyalists. They, unlike all other types of Covenant, can fly without using technology (such as jet packs). They're used for surprise aerial ambushes and assaults, such as catching Human troops off guard and causing them to shoot upwards as a diversion so that their allies may attack on the ground. This is a common Covenant tactic used to wipe out a whole squad of UNSC Marines.

In Halo 3, Yanme'e can be seen lifting UNSC Marines off the ground (Such as in Crow's Nest), to considerable heights considering a Yanme'e's thin, fragile-looking body. This suggests that Yanme'e are stronger than they seem, possessing incredible strength contrary to their appearance. Although real life insects sometimes have disproportionate strength

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. Since they appear in swarms, they can often confuse or disorientate the enemy, which gives them an advantage over fewer, slower-moving enemies

. Drones also have the distinction of being able to board vehicles. They do not seem capable of driving them, but will claw mercilessly at the driver until he is killed or gets out of the vehicle. However, their melee is weak, you can simply wait it out until someone shoots it down or simply crash into a structure, causing it to lose its grip on you. Their capability for limited flight allows them to easily weaken an enemy and retreat as necessary when in danger.

They wield lightweight weapons such as the Needler and Plasma Pistol, though they never charge up a shot of their Plasma Pistol to break a shield, as with Jackals. They also enter battle in a swarm (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 and difficulty level. This is most likely due to a natural physical weakness, as the sniper rifle's shot would likely travel straight through the exoskeleton and cause the Drone to go into a state of shock. Drones never dual wield or have heavy weapons because they can only become airborne while lifting a small amount of weight. When fighting, they have to take frequent rests while in the air, probably due to the gravitational pull from Earth and High Charity. However it is unknown if they can last longer while in space. They are said to have replaced the Elite Rangers after the Covenant Civil War began, probably due to their inherent maneuverability, skill in Zero-G combat, and incredible aim. Even though their weapons aren't very effective, be wary of their incredible aim because too many hits even from a weak weapon can be fatal. It has been noticed that the Spiker and Assault rifle are the best weapons against Drones, and when dual-wielding anything, you can literally shred your way through a swarm.

On Easy and Normal difficulty, the Drones are easy to kill and present no real threat; however, on Legendary, they can be an extremely deadly enemy to face. Their ability to fly means that if you have cover, they can still fly over and around you, and due to their pack mentality they can outnumber and kill you very quickly. Individually, however, they are still rather weak in resistance. One tactic is to lead the pack into a narrow corridor and throw any kind of grenade at them. Most of the time this tactic will kill a majority of the swarm.

In Halo 3, Drones have the ability to lift Marines from the ground, similar to the Brutes. The only time this has been witnessed is during scripted events, and if you kill the Drone in question it will let the Marine go. They have also kept the ability to board vehicles and melee the driver.

There is a moment in the Halo 3 level Tsavo Highway where approximately twenty Drones swarm out and attack you and your passengers in whatever vehicle you currently have. On Easy, Normal, and sometimes Heroic, the Marines will shred through the Drones with minimal fuss, but on Legendary it is a battle to be reckoned with. In addition, on the level Crow's Nest after the bomb is activated, a huge swarm of fifteen or so clumped-together Drones will fly past you. If you throw a plasma grenade into their midst it will usually stick one and kill most, if not all, of them. This will incite the wrath of any nearby Grunts and the remaining Drones.

In Halo 3, Yanme'e can pull you and other team mates out of vehicles.

Tactics
Drones are weak, even more so than Major Grunts but about as strong as Minor Grunts. However, in large numbers (as they travel in swarms), they can be more deadly than Brutes. First, find cover. If you recklessly charge in headfirst, you may take out some of the buggers, but your shields will be overwhelmed, and you will be cursing your fate as you see the Drones shoot your corpse. Then, switch your Energy Sword (not too far, as it is quite useful against other enemies) for a SMG or Covenant Carbine. In addition, you may wish to get a Battle Rifle/Sniper Rifle. First, through a hole or crouching, snipe a few out the air. Then, duck and wait for them to forget about you. Repeat this as many times as necessary. Then, switch to your SMG for cleanup and pick off the few lone survivors (shouldn't be too arduous). Alternatively, you can employ the Plasma Pistol and overcharge each one out the air. Of course, after one or two overcharges, duck down to cover to allow your shields recharging time. Another tactic would be is to get a rocket launcher and wait for them to get in a group then fire or get dual wield SMGs or plasma Rifles. The main essenal tactic, though, is to use fully-autommatic weapons. Sniper Rifles will maybe only take down a few out of dozens, and plasma grenades might as well pass through them like thin air. Assault Rifles and SMGs are the the best common weapons against them.

Halo 2


Drones were first seen in the game Halo 2, after a long period as combatants during the First Battle of Earth, and were featured often in overwhelming swarms in open spaces. They had less distinguished, shinier, chitinous armour, and much smaller, luminescent eyes and a less insectoid and more alien-like appearance. They are enemy combatants in the following levels: A single swarm over the elevator on your way to the bomb. A swarm at the end of the courtyard battle. Another later in the tunnel. Some swarms near the end of the level. Several swarms during the level. This is the level with the most Drones. Several swarms fighting on the Loyalist's side. Some are having aerial battles with Elite Rangers. A swarm in the first room of the structure shortly after you meet up with the other Elites. A single swarm of oddly colored Drones (of an unknown rank) with red/purple armor fighting Flood Combat Forms.They may be Councilors. A single swarm before the final inside Brute battle on your way to the Scarab.
 * Cairo Station
 * Outskirts
 * Delta Halo
 * Regret
 * Gravemind
 * Uprising
 * High Charity
 * The Great Journey

Halo 3


Drones appear a few times in the game but when they do, they are nearly always in swarms of thirty or more. Here is the list of levels that Drones appear in:
 * Crow's Nest
 * Tsavo Highway
 * The Storm
 * The Covenant

The best tactics for dealing with a Drone swarm is to hide behind cover and take the Drones down one at a time. Also, if a Drone boards a vehicle it will claw at the driver until they are killed, a certain amount of time has passed, or they themselves are killed. An effective, but dangerous way to remove them from vehicles is to ram the vehicle into a nearby wall or large structure. This does, however, risk the destruction of the vehicle and possibly death.

On the level Crow's Nest, if the player is vigilant enough, he/she can take and save a Deployable Cover from the hangar. After the Drones grab a Marine (seen through the mesh), run to the left and place it in front of the .50 Cal Turret. Doing so will enable one to shoot through and kill while avoiding the incoming Plasma Pistol shots from the Drones. Since Deployable Covers are commonplace on Crow's Nest, all the player needs to do is to seal up the pipes and keeping them from coming out.

One more simple and effective tactic to deal with Drones is when they are in a swarm, all that is required is a sticky grenade to stick one of them in the center, or an explosive (such as the Rocket Launcher) and most, if not all of the swarm, should be wiped out.

The projectiles Brute Choppers fire can easily kill drones in one or two hits. This tactic can be used while sitting outside the first blue energy field on the level Tsavo Highway.

Brute Shots are also very effective when the Drones are in a cluster. Rapid firing three will destroy most, if not all, of them. Rocket Launchers and Fuel Rod Guns are devastating on Drone swarms. If one takes the Fuel Rod Gun from the Brute Chieftain in the Ops Centre in Crows Nest, he can fire it at the swarm of Drones a little further ahead in the level and can kill almost the entire swarm in one hit.

Trivia

 * Drones can board/hijack vehicles in Halo 3, but instead of kicking you out of the vehicle, their attacks quickly kill you on higher levels.
 * The multiplayer map Guardian has visual similarity to the description of the Drone's homeworld Palamok, and the sounds of Drones can be heard in the background.
 * The nickname "buggers" is possibly a reference to the insects from Starship Troopers, or the Formic race in the Orson Scott Card novel Ender's Game.
 * Although the Drones have been a part of the Covenant since at least before 2525, they were predominantly used as technicians on board vessels until their effectiveness in combat was discovered during the attacks on New Mombasa.
 * The markings on their outer shells are similar in appearance to the Plasma Pistol charge meter. They also resemble the camouflage markings on some real-life insects.
 * Despite their primitive appearance and mentality, Drones are actually an advanced race, and have attained "Tier 2" on the Forerunner Technological Advancement Scale.
 * They cannot be infected by Flood, since a Drone has no basic skeleton upon which the Flood organism grafts its biomass into. However, the chitinous shells may be used as a source of calcium.
 * In Halo 2, if a Drone is shot and killed in a certain way, their wings will jut out from their coverings like they were about to take off similar to that of a swatted fly or mosquito. This also happens in Halo 3. If you kill them, their wings will still be out on rare occasions.
 * Drones are one of the few Covenant species that are predominantly left-handed in the game.
 * In the novel Halo: Contact Harvest, the Drones are described as copper colored, but they appear green in the games.
 * It is believed that the Drones with the Needlers are ranked higher than other Drones.
 * The initial Prophet designs eventually morphed into what we know as the Drone.
 * In the Halo 3 map Rat's Nest, if you listen near the pipes around the map, you may hear drones inside scuttling around and bumping into each other.
 * The Drone's name, Yanme'e, is probably based on the Japanese 蜻蜓 (yanma), meaning large dragonfly.
 * The Drones have green and greenish-yellow blood instead of blue blood like other Covenant (except the Prophet of Regret which has red blood like John-117 and other marines).
 * The Drone is the only Covenant species not to appear in Halo Wars.
 * The Drone's name and appearance is similar to that of a Pokemon in the Pokemon series (Yanme'e, Yanma).
