Hit the tyres/wheels and you have an "M Kill". That vehicle isn't going far or fast especially in a desert/middle eastern road infrastructure. Plus the British Land Rover isn't particularly reknown for it's ballistic resistance LOL
We have these MRAPs that supposedly can travel 30 kilometers with shot up tires, or rounds to the engine block/coolant system/etc.
I personally don't believe it, but I'll never get a chance to ride in one : /
Not likely given the short distance, but it would have been hell if the shooter had missed one to the windshield.
