I wanted a Voltar that was reminiscent of the Real American Hero version, but dropped then fuchsia color in his uniform. Red was suited to the Iron Grenadiers and it seemed like a logical jump. I adapted the ARAH backpack for the 25th insert by cutting off the old tab and replacing it with a small piece of 1/8" plastic rod that I ordered from a hobby supply store. I used green stuff to mount it in the backpack.
