            "description": " Jacq-Hergoualc'h (2007 [1979]) discusses the royal army and its weapons examining the bas-reliefs of three temples: Angkor Wat, the Bayon, and Banteay Chhmar. The bas-reliefs of Agkor Wat depict the conquests of Suryavarman II (1113-c. 1150 CE), while those at the Bayon and Banteay Chhmar depict the conquests of Jayavarman VII (1181-c. 1218 CE). Thus, the detailed bas-reliefs of these three temples allows the scholar to examine Khmer military history spanning roughly one hundred years. Unfortunately, Jacq-Hergoualc'h does not make explicit (or quantify) the evolutionary changes over this time period. The earlier military technology at Angkor Wat depicts 'the most basic weapons, essentially lances, bows and arrows, and bucklers, sometimes in tandem with breastplates' (Jacq-Hergoualc'h 2007: 173). As noted by Coe (2003: 186), '[f]ar more sophisticated armament is to be seen on the Bayon and at Banteay Chhmar, especially among the infantry. This includes the ballista, mounted either on elephant back or on a wheeled vehicle that could be rolled onto the field of battle [...].' According to Jacq-Hergoualc'h (2007: 35), none of these 'big machines' are present on the bas-reliefs of Angkor Wat, the construction of which (c. 1113-1145 CE) pre-dates the great battles with the Chams during the reign of Jayavarman VII (beginning in c. 1181 CE). Furthermore, the emphasis on horses diminished and chariots were abandoned in favor of a more developed and elaborate corps of elephants surrounded by infantry."

At that time the MilTech codes would be the same as for the preceding Yuan China. Over the next decades the state lost territory and there was civil war at the start of the 15th century although in 1409 CE they still managed to rout a very large invading Ming army. The Ming attacked again but the Mongols were not conquered. Under an Oirat noble called Esen (1440-1455 CE) they invaded China in 1449 CE with 20,000 cavalry and captured the Ming emperor. In 1451 CE Esen overthrew the Mongol Khan but he wasn't a direct descendent of Genghis Khan and was killed during a 1455 CE rebellion. His rule was followed by minor Khans who ruled a Mongolia in which the Khalkhas were one of three 'left-flank' tumens (in addition to Chahars and Uriangqais). The state also had 'right-flank' tumens (Ordos, Tumeds, Yunshebus) and the Oirats of western Mongolia. \"These 6 tumens were major administrative units, often called ulus tumens (princedoms), comprising the 40 lesser tumens of the military-administrative type inherited from the Yuan period, each of which was reputedly composed of 10,000 cavalry troops ...\"§REF§(Ishjamts 2003, 208-211) N Ishjamts. 2003.
