Devil Dogs in Kilts?

[macwilkin]

Please 'splain for us non-military (or at least for me!): what is a Devil Dog and a Jar Head? Is "jar head" because of the hair cut? And, since we are at it, what is the derivation of the term "leather neck"? Are there any other names that I need to be "up" on?
THANKS for the explanations and for your service!!

For an interesting article about the "Devil Dog", please visit:

The author provides a very interesting & respectful look at the "Teufelshunde"/"Devil Dog" story from WWI. He also does mention his sources.

Regards,
