Are you serious?? Never approach troops in a combat zone if you can help it. There is no guarantee that they won't mistake you for a suicide bomber. Stay far away from any
Israeli troops unless they explicitly offer to evacuate.
Stay in your hotel. The Marines will evacuate.

see post #132. I think TBN knows what he's talking about.
I am for real if he has his ID Papers in hand and approaches them with palms up, he will be just fine. The troops will shout direction to him, I would approach them shirtless as well.
