If what I have said offended you...
So I was reading Brocks thread about the archaeology student who found an Australian soldiers remains from WWI and said soldier had a German helmet. I knew the Germans had a spiked helmet, but only now have I ever wondered why. Don't the Germans have some really tall people? Tall person + good sized spike on the top of the head = bad head clearance. There doesn't seem to be too much of a tactical advantage to it, and it seems to get in the way too much for it to be worth use as a decoration.
... then it was probably intentional.
