Hey Raven! I think I'm a REMF but here I am...
Went to Saudi back in '90-'91 with an Army Reserve Escort Guard (EPW transport) unit, the 342d. Actually, it was more "adventures in babysitting," but we didn't know that when we shipped out after three weeks at Ft. Meade boning up on dusty mustard, MOPP fashions, supposed Arab culture, etc.
Yeah, I could say I was in contact "with the enemy," and I went on "missions." Well, I DID! Some missions were practically 24 hour affairs, some in sandstorms, but they were mostly cake walks, and I never went for more than about that 24 hours without a shower.
I took a Gerber Mk. II and my Buck Scoutlite. Had a bayonet too, for my M16.
I wish I'd had my smaller Camillus Pilot Survival knife though. Cut some commo wire one time with that Gerber and dulled it nicely on both sides!
I remember seeing DOD civilians around the port of Dammam. Where you're going, you should have a pistol, but we all know about "regulations." Your life ain't worth s*** to the rulemakers.
Since you don't haul a rifle, you might like a bigger fixed blade, along with a multitool and a nice folder (or two). If capture is a possibility, consider something small and hidden, for E&E purposes, mostly. Maybe even something sewn into your garments? A neck knife, like a La Griffe, perhaps.
The first time I used a phone to call home in Saudi, I was with one other GI, unarmed out of our compound, with only my Bucklite in my pocket and all these strange folks around...sure coulda used a nicer blade, if only to feel a bit "safer."
How's that for REMF advice??
BTW, I missed out on all the GRAVY.

But I have BEEN THERE ( shopping at the Al Khobar mall!) and I DONE THAT (took a MOPP 3 dump in a dam squatter

funny how the sounds of unknown explosions and unintelligible radio traffic makes one nervous on the first day of an air war

).
Stay safe, dude, and good luck!
