And that elephant *saw some shit*. It was a 'Nam war vetephant with PTSD. And it's not like it could just forgot.

You think the elephant had PTSD? Could you imagine the poor Roman legionaries facing off against these things?

Most of these romans had never traveled more than maybe a  a hundred kilometers max from the town they were born in and that is being generous and only for a lucky few who usually had jobs that necessitated it. What would be going through your head If you suddenly had to fight a 10 foot, 13,000 pound monster with horns and a trunk capable of throwing an entire adult man? You would have never seen anything in your life that could have come close to that. you couldn't even imagine anything remotely similar. Then add on top of that the fact these elephants were armored and piloted. 

If that didn't give someone PTSD I don't know what would.
