Alpha Strain-Milites: The Milites were bred to serve alongside the Legionaries and Centurions, acting as light aerial infantry, made to engage and overwhelm the enemy in large swarms, unfortunately for the Milites, they're by far the weakest of the Alpha Strain, an individual could not pose much of a threat to a even the greenest of terran soldier.
-Legionary: The core of the Dathu servitor armies. The Legionaries, like all other Yanthu, primarily created as a counter human soldiers, and from birth are ingrained mentally with standard battle tactics and strategy, just enough information to give the most novice of troop something to fear.
-Centurion: The Centurions are a grade above their legionary brethren, and are given more autonomy on the battlefield, acting as low ranked officers in the swarm, leading other Yanthu into battle if a Dathu Overseer were not to be present.
-Juggernaut: The Yanthu Juggernauts are truly a fearsome sight to behold. Clad in heavy armor and equipped with a plasma lance cannon, as their name implied, the Juggernaut's primary purpose was to act as shock heavy infantry or in some cases, acting as living weapon emplacements for Yanthu ground forces. Juggernauts are also known as deadly melee combatants, using their blast shield as a makeshift blade to cut through enemy infantry.
-Umbra: The Umbra are a unique sub-strain among the Alpha Yanthus, taking on an authentically humanoid shape, unlike their vaguely humanoid or beastial brethren. The Umbras serve as an Infiltration Unit, bred to operate independently behind enemy lines, or as snipers in an active warzone. With such a role, the Umbra are giving even greater autonomy then the Centurions and Praetorians.
-Praetorian: By far the highest tier among the Alpha Strains and the fewest in number, the Praetorians serve as the personal bodyguards of High ranking Dathu Commanders, Matriarchs and even the Queen Mother herself.
Omega Strain-Ravager: The Main frontline fighter of the Omega Strain. The Ravagers are medium-sized berserk warmachines capable of untold destruction and death on the battlefield. They are moderately-armored, their large mandibles and various limbs are all capable melee weapons able to shred enemy infantry to bits. The Ravagers and their Omega kin often are the prime choice of Dathu Brood Masters as the first wave of a Dathu Invasion. In the middle stages of a Dathu Invasion, Ravagers become a sort of warhound for the Alpha Strain Yanthu.
-Reaper: Reapers are the aerial shock troops of the Omega Strain. Reapers are designed similarly to the Ravagers, with all their blade-sharp limbs and mandibles being capable melee weapons. Reapers are primarily skirmishers, sent to scout out and often harass the enemy via a hit and run strategy. Reapers are armed with poisonous stinger darts which can be shot out from their posterior.
-Behemoth: By far one of the larger members of the Yanthu overall. Covered in thick armored platting comparable to an Alpha Juggernaut and standing at ten meters in height, The Behemoth is a living siege engine, acting as the ultimate terror weapon, although the same could be said for the entirety of the Omega Strain.
-Decimater: The Omega Decimater serves as a sort of living tank, and to a lesser extent, serves as a lesser terror and siege engine compared to the Behemoth, but it has its purpose. Due to it's more small size, the Decimater often is ideal as Anti-Infantry beasts, making use of the highly corrosive and flammable substance deep within their bodies. As the name implies, and at will, a Decimater can eject the substance from their nozzle and wreak havoc to any infantry formations that dare stand in its way.
