Small Scale Military Headquarters

Which 21st Century tanker (or tank w/ tanker) came with the removable helmet?

That would be the origional M-48 (mainly some of the later versions found at TRU), as well as some of the figures that came with the origional woodland cammo M2 Bradley, which were also the old Viet Nam M-48 commander. More recently, "COED" Sherman tank repaint in the USMC markings came with a XD Marine figure that had a removable WWII tanker helmet. You can now find a couple German tankers from the BoB2 series of figures that have removable hats and while supplies last, there's the surplus 21c Viet Nam figures, which all have removable tanker helmets.

Oops, sorry I wasn't specific (but big thanks Tman for covering all era's and conflicts!)

It was the COED tanker I was thinking of.
