They might not be able to fool JDAM's,+++

I don't get how JDAM may hit GPS jammer if latter moves around? How armorers got its GPS coordinates in real time?

Second moment. When one uses expensive munition and air sorty to take out piece of equipment with cost $200 it mean something.
At least GPS jammers fulfilled the task to compel excessive spending of foe. They inflicts damage to military budget.

I didn't hear about large numbers of JDAM's missing their targets. Surely the GPS jammer that was hit was not the only GPS jammer that was used. Also, I haven't heard reports of more than one GPS jammer being hit. Have you? The JDAM has both inertial and GPS guidence capabilities. It also knows that a valid GPS signal should be coming from a satellite orbiting in a polar orbit, not a fixed ground station or even a moving truck or UAV.
