How do we get early praetorians ?

So im late into my republic game now, I just captured Libya and carthage's main capital, as well as a few other important cities south of it. Anyway, its just bothered me a bit that there has been no change in my military forces since the game began, but I was okay with this, as I was sure that at some point Id get to play with those early praetorians Tone boasts in his sig. I figure they are only available in Rome, but i was dissapointed to not see them there.

So i checked around the building list for Rome, but there was no "build castra praetorium" option or anything, so im a bit confused. Do we get early praetorians after the marian reforms, and if so, why ? I thought the later praetorians would appear during that time ?

I get that its probably incorrect to have praetorians during the age of the republic, they did, after all, only appear as a true emperor's guard force after the republic was subverted into the empire under Augustus (though im unsure if he formed the praetorians, I think he did, but i am unsure). Thus, it would probably be odd to see them alongside republican legions. Even still, as a later republic rome-exclusive unit, i think they would fit in well with the current roster. The lack of praetorians is beginning to change my feelings on my fledgling republic .

No, early Praetorians appear after the Marian reforms, with the Praetorian Guard Training Grounds.....late Praetorians come after building the Castra Praetoria
