Hey guys. I have some pictures and a book of the ancient Thai army
Early Thai archer(Nan Chao,AD649-902) and swordsman(Chiang Saen,13th century), they looked no different,whose hairstyles is bunches of hair(look like han people), may have been popular from pre-Sukhothai to the early Ayutthaya dynasty, in the Thai film “The Legend of Suriyothai”, Lord Pirenthorathep was also in this hairstyle when he was younger. In fact,members of Suvarnabhumi Mahayuth also told us on Facebook that the film references a lot of Khmer Angkor murals.
Battle dress of soldiers during the Sukhothai Period, from 1238 to 1448 AD.
Infantry of the Ayutaya period, because of the hot weather they were mostly naked or wore only a short-sleeved garment, and only a few wore leather armor (cloud shoulders).
The Thai officer, as you can see, also has only a more elaborate uniform, which protects the chest, waist and joints with only leather.
This restored image shows Thai soldiers wearing Japanese-like armor (called "dou" in Japan?). Unfortunately I only found this one with a physical reference.
Foreign mercenaries, they look like Muslims
