I was once followed and harassed by an Iraqi soldier because I didn't want one of the oranges he was trying to give me. The only way I could get him to stop was to lock eyes with him and flip the safety off on my M4. His eyes got as big as the oranges he was trying to give out and he proceeded to harass one of our other guys until his commander started whipping him with a tree branch.
Watch yourself. I'll light you up.
