18 would've maybe been too early. But then again it might make sense -after their service the legionaries would be granted farm land; it's hardly likely that an older man could take proper care of such a concession.
There are several sources that give the enlistment age as anything from early teens to mid 30s, this is one of them:
Finally, the maximum age for joining was around 35 years, whereas the minimum age was about 13 years. But these are extreme examples, most recruits joined between the ages of 18 and 23 years. Note that the service period lasted for 16 to 30 years depending on the branch of the Army."
