This is where you need other observational capabilities and ability to strike very fast.
(Cloud punch-through lasers are already available, but I don’t know if any have been deployed.)
Question for any knowledgeable FReeper: Does a pickup truck rocket launcher have a unique sort of thermal signature after launch (parts heated by the launch) that could be quickly spotted, tracked for up to a few moments, and precision targeted?
I suppose one could launch and then toss the launcher in the ditch / on the sidewalk, but even that might take a few moments?
