Colour change on Jetranger
Every aircraft on this page has an identical airframe. As you can see the colour schemes dramatically change how the aircraft appears. 

Pictured here is a Bell Kiowa which is a militarized Bell Jetranger in current service with the American Army. 
The changes are minor only with having a flat windscreen and slightly different rear window design. Therefore it is comparatively easy to repaint a civilian Jetranger to closely match a current machine.
