I'm still new to A-10C and I'm still learning how to pilot the plane, so I've only been doing Instant Action missions thus far, but from what I've noticed, mobile ground targets (jeeps, trucks, tanks, etc...) don't ever run away after you bomb a target around them.
For example, if you attack two trucks and only hit one, the other truck will drive a short distance, stops, and then doesn't ever budge again. Same goes for tanks that are either sitting still or traveling on a road.
Does anyone know if this is common behavior throughout the game, or is this only for the instant action missions to make it easier to attack the targets?
