The Kipchak Confederation was essentially their military elite AND ruling body.
Basically the Warrior Tribes of the Cumans.
" Kimek
The confederation or tribal union which Kipchaks entered in the 8th- or beginning of 9th century as one of seven original tribes is known in historiography as that of the Kimek (or Kimäk).) Turkic inscriptions do not mention the state with that name. 10th-century [Hudud al-'Alam] mentions the “country of Kīmāk”, ruled by a khagan (king) who has eleven lieutenants that hold hereditary fiefs. Furthermore, Andar Az Khifchāq is mentioned as a country ( nāḥiyat ) of the Kīmāk , ‘of which inhabitants resemble the Ghūz in some customs’.
In the 9th century Ibn Khordadbeh indicated that they held autonomy within the Kimek confederation. They entered the Kimek in the 8th- or beginning of 9th century, and were one of seven original tribes. In the 10th-century *[Hudud al-'Alam] it is said that the Kimek appointed the Kipchak king."
Not if they are microed, which is what the Kipchak is supposed to be, at all times.
Think of them as AoE2’s version of the Starcraft 1 Mutalisks.
Left alone hey will just get picked off and not do much, but properly microed they will let out salvos of brutal DPS bursts that will punish the opponent severely.
