GPS Problems?

On the GPS issue, I earlier speculated that GPS problems were not going to be a critical problem since GPS bombs are useful only for striking fixed targets. Strategypage.com reminded me that the special forces on the ground in Afghanistan used GPS/laser range finder combo to strike mobile targets with GPS. Whether that means we can strike moving targets that way, I don't know. The site also reminded me of a GPS strike early last year that went awry. I'd forgotten about that. Were the Iraqis testing their jammers? Reading on, the site says in December we were testing ways to strike moving targets. I guess it is possible, but we probably aren't there yet for anything more than test strikes in an Iraq War. GPS jammers in Iraqi hands are worrisome but not critical. And we may have counter-measures, anyway.
