Triarii

[Rodion Romanovich]

Just like Sheep said. The early Triarii fought with greek style tactics and equipment (phalanx included). Later, after a lot of setbacks against Celts and other Latins (Samnites mainly) the Romans adopted the more well known formation and equipment presented in vannila RTW.

Yes, I knew about roman real life triarii using more greek style phalanx early. What I wanted to discuss was just implementation. To illustrate what I mean, I can mention that a certain Medieval mod even uses the phalanx ability even though there weren't exactly phalanxes in the Medieval era, just because it illustrates well how you had to slow down to hold formation in battle. Anyway, you sollution seems good, pretty much what I wanted as it reflects limited mobility of early and slightly more mobility for late.

Anyway, since the answer was "yes for early, no for late", I have to ask: how will the units perform compared to each other? Which of the units get best kill/death ratio when taking a cavalry charge heads-on, and what unit can handle charge to left flank, right flank and rear better, and how much better? Also - which unit wins and heads-on engagement early triarii vs late triarii? And finally - how strong will triarii be compared to the average greek and macedonian line-filling phalanx troops?
