Get real and stop attention whoring.

I guess I was absent on the day when they taught us to drive civilian Nissans over battle-damaged roads meant for tanks/HMMWVs

The only reason why I said such a thing is because you list your location as Iraq. Obviously you're not really in Iraq. Even if you were, you're not using a Nissan for military purposes. With that said, if you don't know when to use 2WD or 4WD then you could consider that the least of your problems since you obviously haven't been trained with any kind of driving experience in the military. Or you could update your profile and be truthful.

I've concluded he's a fake.

ETA - I don't care if he's a lifer or not.

If you need to go to 4 wheel drive, they are not speed bumps.

Hmmm...these aren't your every day "speed bumps" as much as they're standard roads destroyed by years of tank/BMP use...A more accurate name might be speed depressions

Though nobody put them there to reduce speed...but tracks'll do that to a road

Well, that's not a speed bump, then.. :p

If my rear tires would spin before pushing my front tires up/out, then I'd use 4wd to pull the truck through.

Well, I wanted something people would be familiar with :p

Tell them you want an FJ40 instead of a Nissan. :D

Ha! My only other option is a Cold War era Uaz :D

Think what you like...

As for the Nissan, I'm using it for military purposes. Perhaps you meant to say I'm not using it for tactical purposes?

With that said, if you don't know when to use 2WD or 4WD then you could consider that the least of your problems since you obviously haven't been trained with any kind of driving experience in the military.

1) Officers receive no formal driving training
2) No one AFAIK receives driving training on civilian vehicles

Yes, the general consensus seems to be to:

Keep it in 2H until the vehicle gets stuck (or I'm certain it would get stuck in 2H), at which point, switch it to 4H. By corrolary, I imagine 4H should be used until one would get stuck in 4H, before switching to 4L.

I'd love to clear up some bad info here. Is this a vehicle with automatic hubs? If so, putting it in 4wd after you are stuck is going to do nothing for you. Manual hubs (where you have to jump out and turn the dial on the hub itself) will give you 4wd right at that second, so that could help you, but automatic hubs need 10 feet or so to lock up.

As for bumps, there isn't much of a reason unless that are REALLY bad. I 've run lots of tank tracks and they are usually 2wd

I believe manual hub. FWIW, vehicle is a Nissan Patrol.

If the center of the front wheels have rotating hubs (lock / unlock), then it's manual hub. :)

Option 3: Shift-on-the-fly..automatic disconnecting differential, full-time locked hubs. I doubt that's what he has, though..

Yes, but apparently something's "FREE" and something's "LOCK" and you turn something clockwise or counterclockwise :)

If you'd like, I can tell you what the words are phonetically, but probably could tell you the meaning of no more than 1 in 10 :(

First line is "Don't tefud the car on wuhsaa the duqaa on the 4"

I disagree. First of all, the vast majority of roads don't need 4wd, even dirt, gravel, and some mud. However, if you DO encounter enough mud to pose a problem, switch it into 4WD BEFORE getting stuck, plan your route, and go in in a low gear, at a steady speed. You shouldn't wait until you get stuck to switch it to 4WD.

lmao, nice try

Freely moving pretty much means "unpowered" here.

Warning:
Do not drive the car when it is in 4WD mode (4H or 4L) if the freely moving wheel pair (it actually says axle) is in FREE mode.
Do not drive your car if the left and right axle wheel locks are set differently.
For the first 500 KM, it is suggested that you drive in 2H mode. You should also set the locks for the freely moving wheels to LOCK mode.
In order to properly oil/grease the components for FWD drive the car in LOCK mode for at least 16 KM monthly

The manual locks for the freely moving axle
The wheel locks for the freely moving axle have been designed so that you may engage and disengage engine power to the front tires. Before driving, set the wheel locks for the freely moving axle to the proper setting.
Enabling 2WD - Twist the lock to FREE mode
Enabling 4WD - Twist the lock to LOCK mode

Not exactly sure what the very last part with the arrow and the dot means, but its basically saying to pay attention to the markings on the lock and on the wheel.

Oh, and you confused some letters. It says taqud (drive), wad' (condition), and daf' (when put with condition, it means being pushed or being powered).

No problemo. Once you've got the hang of the letters Arabic's pretty straightforward. 3 letter root words for a large portion of Arabic vocabulary makes it easy to speak once you've got the grammar down. Good luck in Iraq :)

When I was in the states I used to go to Pismo a lot. (California State Park for offroad vehicles to play in the sand dunes) Before I ever left the hard packed sand near the waters edge I would switch to 4wd and air down my tired. If I didn't do both, there was a pretty good chance I would get stuck, especially when I hit the softer stuff, or anything on an incline.

Believe it or not, I've made some good progress since starting out with the language. The first time I saw the transliteration for small--zghayer--I thought I'd never get it.

I mean come on, the letters ZGH in a row...who does that? :)
