name of a special ability

How do I change the name of a special ability.
eg.
changing the word shield wall to phalanx.

If you literally just mean the word, you'd change references in
data/text/battle.txt

eg

Quote:

---

{BMT_SHIELD_WALL_SPECIAL} Special Ability: Shield wall

---

to

Quote:

---

{BMT_SHIELD_WALL_SPECIAL} Special Ability: Phalanx

---

just don't touch the parts inside the {}

You can actually use the phalanx ability in BI as well though if you want to. You just need to change change "shield_wall" to "phalanx" for the relevant unit in export_descr_units.txt

Phalanx's seem to have a lot more advantages in the game so that might be worth doing.
