I also remember that I created a post where I suggested that the Incan civilisation could train a new military unit that would be called the “Kumana Prowl Runner”.
These Kumana Prowl Runners would basically be the Incan counterpart of the [Eagle Runner Knight] that is available to the Aztecs as a ranged cavalry substitute. And as you can tell from the word “Prowl” in their name, the Kumana Prowl Runner will also have the ability to go into stealth mode at default without needing the “Cloud Warriors” card.
“Kumana” apparently means “Spear Thrower” in Quechua. The reason for giving this spear throwing military unit a stealth ability is because when the Incas later adopted the Spear Thrower as a military weapon, they did then use it mainly in guerrilla tactics to attack the Peruvian cavalry.
Here is a link to the post for anyone who is interested:
