Much of the movie "Pulp Fiction" centers around a briefcase and its mysterious contents - an item or items of incredible value and importance never revealed to the audience. It's a classic MacGuf-fin, an object in a film that matters only insofar as it motivates the characters and propels the action. And in some ways, the joint all-domain command and control, or JADC2, concept is the Defense Department's MacGuffin - it's not clear what it is or what it looks like, but it has become one of the driving forces of military modernization and transformation. The bumper sticker for JADC2 is straight forward: sense, make sense, act. The idea is to link sensor data to command centers to "shooters" -destroyers, jet fighters, missile batteries or ground troops - to take quick action against a target. But JADC2 is far more than a bumper sticker, and things quickly grow complicated when it comes to building resilient command and control across domains that can function in contested environments - something the military did not face during 20 years of conflict in Afghanistan and Iraq.
