if they deploy, they always do it the same way. en never use their skirmishers
the correct way ( they always skirmish the wrong way when charged, always away from the main battle line. at least the numidians do that alot in my gamews. )
and they only flank with javelin cavalry, if they flank at all.
but I have never ever seen the AI do any hard tactical maneuvers (?)and also I've never seen them deploy in any other way than the 3 line formation.
this al is on the medium / very hard (battle/ map )
