A paper about how the new technologies failed in Iraq (sensors and communications networks as on heavy armor and huge numbers.) in MIT Technology Review. I am definitely not a military freak but some insights good be drawn from it.

Yet connectivity in Qatar was matched by a data dearth in the Iraqi desert. It was a problem all the ground forces suffered. Some units outran the range of high-bandwidth communications relays. Downloads took hours. Software locked up. And the enemy was sometimes difficult to see in the first place.
