I guess alot of dimensions will be off, but I wanted to give this a shot. Maybe it would help if I had a reference picture too lol.

The S Tank (Stridsvagn 103). The first time I saw it I believe was in the old game 'Assault Rigs' which I played on the Playstation One back in the day. Or roughly something similar looking to it was in the game.
I remember my father saying the name "S Tank" which watching me play this game. So I started looking up stuff about the tank.

For starters - It lacked a turret. Still it was called a tank. It was not classified as a tank destroyer like those back in ww2.
It has a story behind it which is longer than I can write here, but I do recommend looking it up on Wikipedia or Youtube.

The weird wedge shaped design always interested me though. And I guess it is from that tank my fascination with sharp edges comes from.
It always felt a bit sci-fi to me though. And in one of the expansions for Battlefield 4 (which expansion I never played) the tank returned as a hover tank. An idea I liked since the tank could strafe in Assault Rigs, but I wanted to give my take on it.

Consider this more training for me. I would like reiterate on this design later.
