This seems like the digital equivalent of adding skulls to your officer's caps -- how have these guys not realised that they're the baddies yet? ( http://www.youtube.com/watch?v=hn1VxaMEjRU )
The use of skull and death motif goes back the Napoleonic wars with Brunswick Hussars. Hitler and the Nazis where very good at nicking their imagery - I suspect Hindus are still at bit pissed off over the swastika
Actually, it goes all the way back to the War of Austrian Succession and Prussian Husaren-Regiment Nr. 5.
As a long-time student of history I get very annoyed when Nazi symbology is presented as something they invented, particularly when used to demonstrate that we should have known they were evil to begin with. They ripped all their shit off from someone else, and some of it is only viewed as evil today because of them.
