Proposed Unit Roster (Draft)
Non-Combat Unit
Woman-Trader - Quite uniquely, Khmer traders are all women.
Khmer faction does not have “trader” unit. Instead their women double as trader.They carry (much) less goods than actual trader from other factions, but you can swarm the market with them.
Healer (Hinduism or Buddhism)
Fishing boat
Citizen Soldier
Spearman
Archer
Crossobowman - Continental SE Asian crossbow seems to be pretty weak, without stirrup or other spanning devise.
Skirmisher
Phkapman - Welding a phkap, a sickle-like polearm unique to this region.
Light Horseman
Chariot
Champion Unit
Nayar (Swordsman-javelineer) - I keep hearing this so-called elite army, a spartan-like warrior caste of the Khmer Empire. But the source is solely lacking. So I will omit them for now.
Maiden Guard (Spearwoman)
Auxiliary/Mercenary Unit
Siamese Auxiliary
Lavo Auxiliary
Chinese (Song Dynasty) Auxiliary
Elephant Unit
Worker Elephant
Elephant Archer - As far as I am aware, Khmer was the only people to use the "double basket howdah" design for their elephants. This clever design makes their elephant archers much more effective compared to the "everyone sit on the elephant's back" approach, as all archers can shoot at the same target without getting in the way of each other.
Siege Crossbow Elephant - Unique unit of the Khmer Empire. Combines the ranged firepower of a double-bow siege crossbow with the close combat capability, mobility and resilience of a war elephant.
Siege Weapon
Double-bow Siege Crossbow - The Khmer probably learned this weapon directly from the Chinese, or through their Champa rivals.
Shielded Cart/Manlet
Warship
Longboat
Heroes
Jayavarman VII (Chariot) - Most powerful warrior-monarch of the empire and the builder of Angkor Thom and Bayon Temple.
Suryavarman II (Elephant) - Builder of Angkor Wat
Wonder
Angkor Wat - Maybe making entiry city a wonder is too much.
Gold Temple of Bayon - It is a stone temple covered with literal gold. Only the stone part remains though.
Easter Egg Unit
Stegosaurus - No, seriously.
