This is tag for real or fictional tank and tank-like armored military vehicles featuring a casemate (turretless) design with the main gun mounted directly within the hull of the vehicle. Advantages of such designs were that they were mechanically simpler than turreted designs, less costly to produce, lighter in weight, and lower in profile. Due to taking up less weight in the design, heavier armor and/or armaments could be added onto the chassis. A primary disadvantage to this design was that the main weapon was affixed with a limited fire arc in the front and thus required the entire vehicle rotating to be able to target things outside this arc.
