"No. He was a message runner in the List Regiment for most of the war."
Hitler was twice decorated for bravery. He received the Iron Cross Second Class in 1914 and the Iron Cross First Class in 1918, an honour rarely given to a lance corporal. Hitler's First Class Iron Cross was recommended by Lieutenant Hugo Gutmann, a Jewish adjutant in the List Regiment.

In all the accounts I've read of Hitler, by William L. Shirer and John Toland as well as others Hitler was only ever decorated with the Iron Cross/Second class which would have been a rare honor for an enlisted man.
In accordance with German military regulations the Iron Cross Second class was worn over the left breast pocket and could be worn with or without the Second Class ribbon which would have been looped through the second button hole on the tunic.
The Iron Cross First Class was always worn at the collar(or throat).
I've never seen a picture of Hitler wearing an Iron Cross First Class.
