Roman Army Drill

[Scipio_Africanus]

Hi,
It's my first post too ^^.

So I've read pratically all the post of this topic, but i would like to discuss the theory of no manual for the early roman. Gary's post
I'm disagree, because i think it was more complicated that just oral exercise and transmission in vocal type.
With this type of, the drills could be probably too much personalized by the men (centurion and other officer) in charge of train the troops, for the roman army.

In more, with your suggestion in a moment like Varus in AD 9, the roman army could be probably lost a lot of his instructors and would have lost a big part of a military knowledge hard acquired in the past.

Because of that, I think roman army had a lot of drill, depending of the Legion instructor, and the localization of this one. But in manual, gathering of an unknown number of older document.

For the main subject of this topic, I have not a lot reference in different roman author... so i can't pronounce myself for one of them.

P.S : Sorry for my english, it's not my native language.
