Unable to recruit some units in RTR campaign mode

[Strategholos]

Hi I recently started playing Armenia in RTR and I noticed when I clicked to have a multiplayer game the Armenian army has leggionaires. The problem is the legionnaires don't show up to be recruited in my campaign mode. I'm only a couple hours into playing that faction and have only taken 3 other cities. The setting is on very hard and I even used a cheat on my capital to increase population so I could build all buildings to see if the legionnaires would show up but still nothing. How do I recruit them? I also had the same problem with the legionnaires in Pontus, I could not recruit them at all. Please help

You have to wait till the Marian reforms.
Couldn't have nations copying Roman legionaries if the legionaries don't exist yet.

They were really based off the Principles, as were the Legionaries. Romanized troops were described as being part of the Daphne Parade in 166BC? This is ~60 years before the Marian reforms.

Indeed. All part of the gradual homogenisation of arms and troop types in our area. Or least that's what I've seen written elsewhere in these fora
