you can send a "bluey" to a serviceman, get one from your post office and address it to:
a serviceman in Iraq, Afghanistan,\Bosnia,\Kosovo
it will be gratefully recieved belive me, you WILL get a reply, soldiers love getting mail from home especialy from people they dont know but who appreciate what they do. Hope it starts a beautiful friendship, Im still in touch with a lovely lady from Redditch who wrote to me while I was in Bosnia, we've been firm friends since 1995
Good luck.
