Your getting plenty of good advice on knives. So I wonder, if You have any high ranking NCO buddies that can get you a M-9- 9mm aka Beretta 92. Cause if you can lay hands on one over there and a couple mags with ammo, maybe you should take a good concealment holster along., then get the pistol once in country, from somebody that trusts you to give it back when you leave. You would have to keep it concealed, but if your not going to be searched everywhere you go, its worth a try. If you have to use a knife for anything but utility, they are way too close and a couple 40-50 rounds of 9mm will do you a lot more good. I suppose it would be too difficult and probably get you in trouble to sneak a small pistol or revolver of your own along. Hard to detect pistols in baggage if you break them down. Be nice if they just let you do it. Other than that my first idea might work. Its what I would be trying. Senior NCO's make the world go around. Without them nothing happens.
