Gaemamusa

Overall strategy
The Korean Gaemamusa is in essence a Cataphract-type unit that doesn't need a Magistracy to be trained. However, it suffers from one penalty, and that is its slower train rate. Gaemamusa are best understood to be an exact tactical clone of the Cataphract, and so are meant to be used in the same way as normal Cataphracts ought to be used &mdash; trampling enemy infantry, while keeping away from more dangerous spear units.

Background
The Gaema Musa 개마무사, or "Warrior of the Kaema Plateau" were the elite warriors of the ancient Korean kingdom of Goguryeo. They were some of the heaviest cataphracts to be fielded by a Far Eastern polity, with both the rider and the horse completely encased in heavy armor. Goguryeo was the most militarily dominant of the Korean kingdoms and its cavalry were the vanguard of many conquests.

Aside from their deadly prowess, the Goguryeo cavalry were also distinguished by the elaborate plumes attached to their horse's flank armor: a tradition that bore much similarity to the 寄生 "Jisheng" (Lit. "Parasite") used by the cavalry of the northern Chinese dynasties and the Xianbei nomadic peoples. The plumes of the Gaema Musa varied greatly from each horse, ranging from billowing folds of silk banners to a collection of multicolored snapping pennons.
