I'd very much like to see more transport vehicles in the game, I really don't believe that regular soldiers would have to hoof it as much as they currently do in game, especially long stretches through dangerous open areas.
Therefore, we might benefit from more trucks and APC's
Such as these:

Arriving in style, notice the roof mounted guns on these trucks

And, eh. A humvee I think, but see the cloth cover?

*cough* moving on...
Furthermore, civilian vehicles would be a big hit I'm sure. And not DC's genetic pickup truck (I didn't like those very much) but rather old beaten-up all terrain vehicles suitable for the desert environment, and small scooters and motorcycles, especially like the one on the last picture. great for getting around if you're separated from your group, and a fine mean of transportation if you have been dropped without support vehicles.
Plus, it would add flavour and realism to have abandoned motorcycles and such lying in ditches and leaned against walls.
