Elephants are supposed to be about as smart as a 14 year old human or so (which is genius by animal kingdom standards), ergo you should theoretically be able to teach them things you could teach a child soldier, therefore you SHOULD be able to teach them how to operate some kind of anti-tank weapon.
The question is thus, what anti-tank weapon exists which an elephant would be able to successfully manipulate with their trunk?
Not saying the elephant would be guaranteed a victory or anything, but that the elephant could have a realistic chance to win and survive against the tank if having the weapon and being able to use it.

That might actually work on some lighter tanks, but it's the same problem of plugging the bore with its trunk, the elephant won't survive that either.

That'd be something for survival at least, but the elephant needs to figure out how to eliminate the tank.

This could MAYBE work, but the chance of survival is very low still, those are a suicide attack.
