The standing army of the Inca was formed primarily by nobles, but the Sapa Inca could raise an army of able-bodied men from the general populace at will. Military discipline was strictly enforced when the troops were on the march and the army, although variously specialized, was extremely well trained. Of central importance to the Inca military were the Chasquis, scouts and messengers who could swiftly relay orders and were capable of traveling across extremely long distances as a result of their peak physical condition and the existence of an extensive network of Tambos, inns situated alongside the vast roadways of the Inca Empire. Chasquis were formidable fighters as well as messengers and scouts, however, and their keen senses, speed, and agility made them a challenge for even the most experienced troops in an enemy force.
