I was thinking of doing something similar, but with a specific unit in the US Army; the [url=http://en.wikipedia.org/wiki/90th_Infantry_Division_(United_States)]90th Infantry Division ("Tough Hombres")[/url]

It has a pretty rough and ready history, from following Teddy Roosevelt Jr. on Utah Beach all the way to the liberation of the Flossenbürg concentration camp. Much of their action was in Patton's Third Army. They were also notable for offing any SS immediately, not allowing surrender -- that's where the movie "Fury" got the whole 'kill SS prisoners' theme from.

In much the same vein, I was thinking of using the [url=http://en.wikipedia.org/wiki/4th_Armored_Division_(United_States)]4th Armored Division[/url] as well. They were Patton's spearhead, and the first armored unit to receive a presidential unit citation. Notable members include Creighton Abrams, who made a name for himself at the very forefront of the aforementioned spearhead.

Units like the 90th Infantry Division and 4th Armored Division have a storied WWII history, but don't get as much credit as the 101st Airborne and similar.
