will like i said if the us-army don't mind it then its cool, but then again using their url address in that manner is not real cool at all.
it ok have it on the site but not thier url address like you have there. it copying their url address that part is not cool
by the way real usarmy.com you can get free e-mail account there for 25mb sample:
freaky@usarmy.com there is small drawback will not work with any 3rd party e-mail programs but you can have all e-mail forward to another account like gmail.com or hotmail.com
