Not really sure what constitutes 'military fashion', but I think the US infantryman in WWII looks classic. The Napoleonic French soldiers and British/French/etc around the mid to late 1700's looked cool too.The Nazis looked way too evil, but modern nonetheless! The British Empire in WWII looked terrible, like they are going to church or something. Same with the US in WWI. Oh yeah, and Roman legions look kind of cool.
