What torso does the tanks in campaign Use?

[Tesla]

I Have never really noticed until last week that the tanks in overlords den final mission of campaign use a torso I have never seen before.

Here is the Mechs Torso of mechs in the final level of overlords den

And here is the Tanks.

[Electro - Stelight]

Tank are special ennemy like buggy, their "torso" cannot be obtained 

And for the first ennemy he used the revenant torso ( Epic )

.... What 

Idk but i think all the tanks in the game use the same "torso" (body) , always the same only difference of color of the type and level setting
