Any ideas to make the turret more interesting?
Some ideas:
An IR illuminator or spotlight would be a fit.
Could be mounted on the side.
A empty equipment rack or tie down points.
A full equipment rack or tie down points.
A scantily clad tank girl modeled posing seductively on the side.
Extra road wheels on a hard point.
Crew duffel bags.
A bicycle strapped to the side.
My two cents.
Hope that gives you some more ideas.
