Does the anti-Titan artillery exists in the anime? Reading conversations about Attack on Titan I've heard about the anti-Titan artillery, which supposedly is a very powerful weapon against Titan more than the regular cannons. I dont remember seeing it in season 1 and season 2. Have they appeared in the anime? If so, which episode? or this only exist in the manga?
As far as I remember


  The anti-titan artillery is developed by other nations (other than Eldians and Marleys) to counter Marleys titans. since we are not introduced to Marleys and the world beyond the walls in the anime, I'd say it's too soon to say there is no anti-titan artillery in the anime.
