A SCAR, and unbloused boots. Looks like an SF diorama waiting to happen. (We had SCARs several years ago, although the buttstocks were prone to breakage on the first ones)
SF wore the Marine Corps Modular Tactical Vest back then, but just paint khaki and roll with it if you want to do SF figures.
Here's a potential problem I see with this very nice figure set: By 2008, T triple C was being taught in place of Combat Lifesaver. (ib SF at any rate, who knows what Big Army was doing?) Of course that means suppressing the threat is the first order of business, not dragging your buddy, (who in this case appears to be conscious and able to render self aid) to safety, thus taking two guns out of the gunfight. Not a game stopper, just something to be cognizant of if you're using them in a dio. If there are still troops actively engaging targets then you'll still be in the fight yourself.
As for the driver getting out. well... There are numerous situations where it is tactically okay. But in the case, why not have him drive the hot side of the vehicle between the enemy and the wounded soldier Just thinking out loud.
