The cockpit of the Leo2A5 in SBP is fully and truly 3D. For example you can look into the interior through the hatch when sitting on the turret, or the monitor for the TC will zoom in when you select that device, and you can use the mouse cursor to push the buttons, and can freely move your head inside the tank. However, if that is ergonomic when in battle is something different. Really, you overestimate the value and longtime interest of that. Becasue different to SH3, you will not have much time to always stare at the interior of your war wagon. M1 and M2/M3 also have 3D interiors, but are not interactive to that level the Leo2A5 is.
