I was trying to do "Red Skull" from Captain America and was going to use the German on the right, but the hat on the one the left will look better. Easier to add some filler to a skull to get the right look than grinding away at it. Replace the skull emblem with a Hydra looking thing, and good to go.

It's for my daughter. She spent a lot of time at tank battles while growing up, and is a big Cap'n fan. Pitt with the helmet should work for Cap (driving a Sherman) and RS will have a HL Tiger with some visual "upgrades".
