Not quite the same thing. OP is asking about making Gaia units wander around like deer do. In Gallic Fields, a Gaia soldier is spawned and tasked to go to a certain point.
I think this is a bit myopic. If you have a tech. This tech has been in the game for several alphas now (as most eco techs have been). But in the next release this tech has another tech paired to it, what have you lost? Haven't you now gained an additional choice?
Like, I think a lot of people associate the bright red player color with Romans or Spartans, as 2 great examples.
I associate the baby blue color with the Athenians. One of the Green colors with Gauls. Thinking magenta or maroon with Persians.

Photopea has been the first "photoshop" app I've paid for in years. The developer is one guy, I think, and he actually added a feature based on my direct request (a checkbox to save transparency to alpha channel when exporting PNG; a huuuuuge help when creating textures for 0 a.d.). So yeah, he got my loyalty with that one. It has about 95% of the features as Adobe Photoshop at 10% of the price. And you can still use it for free without paying for it. Paying for it simply removes the side banner ads.
It should be difficult to capture, easy to destroy. It's counterintuitive on the realism scale, but in a gameplay world it makes most sense: the greater reward should be harder to attain.
May I suggest using Photopea? It has a Normal map generator out of the box.
You can also easily alter the channels of the normal maps after they're made.
Could subtitle it.
Gods, Men, and Monsters: Olympia
Then there could be sequels or expansions.
Gods, Men, and Monsters: Destruction of Karnak
Gods, Men, and Monsters: Ragnarok
