I've never exported a military vehicle. I did send my 02 Firehawk T/A to Europe when it was sold. I remember it being very expensive for the buyer and it was a looooong tunraround time.
I have used DAS www.dasautoshippers.com Best bet is to contact them to see what is the best way to go. Usually they use containers. If you are in a rush you can do it by air but that gets quite expensive.
