The digital revolution has transformed the U.S. Army. Soldiers have acquired a host of sensors and communications gear that enables information dominance in the fight against terrorists and insurgents. However, in the fight against more capable adversaries like Russia, all that digital gear could be negated by enemy jammers, even the GPS receivers. The Army used to have a fairly potent electronic-warfare capability during the Cold War, but it has largely withered away. In contrast, Russia, China and other potential enemies have kept their edge (if not enhanced it). The U.S. Army needs to bolster its capabilities in jamming and countermeasures to avoid being defeated in the maneuver space that we call the electromagnetic spectrum. I have written a commentary for Forbes here.
