Grand Army of the Tuigan

The Grand Army of the Tuigan, also simply called the Horde, was a formidable fighting force that was assembled by Yamun Khahan and rose to prominence in the Hordelands during the 14th century DR.

Organization
Formed mostly of horsemen, Yamun Khahan's army was fast, efficient, and lethal. The army was organized as follows:
 * Arban - group of 10 soldiers, led by one sergeant
 * Jagun - 10 arbans or 100 soldiers, led by one commander
 * Minghan - 10 jaguns or 1,000 soldiers, led by a khan
 * Tumen - 10 minghans or 10,000 soldiers led by individuals selected by the Great Khan
 * Army Commanders - sons or trusted generals of Yamun Khahan, each had command of 2–6 (or more) tumens

Yamun Kahan's army numbered some 300,000 strong during the height of its power. However, their main strength lay not in sheer numbers, which they certainly possessed, but in the accountability of each individual soldier. If one man within an arban committed a crime, then all 10 men of that arban were punished. Similarly, if a single man distinguished himself during combat, then all were praised and honored. This iron-willed mentality transformed simple soldiers into something far greater.

Tactics
The Horde always carried four times as many horses as men. This allowed for their swift movement which often made it easy for them to surprise and surround their slower adversaries.

Base of Operations
Though they rose to power on the vast steppes of the Hordelands, the Horde ranged over a considerable amount of territory including Semphar, Khazari, Shou Lung, and parts of Faerûn such as Thay, Thesk and Rashemen.
