By Paul McLeary on March 03, 2021 at 7:03 PM Lt. Gen. Dennis Crall, J6 director at the Jan. 26 JADC2 Data Summit WASHINGTON: The Joint All-Domain Command and Control (JADC2) strategy document could land on Defense Secretary Lloyd Austin’s desk within the next week, but the head of the Pentagon effort says huge hurdles remain to actually make it work. Lt. Gen. Dennis Crall, who leads the Joint Staff’s J6 command and control directorate, said Tuesday the options being presented by industry for connecting far-flung forces have been lackluster. “I am looking for good enough and I have not found a good enough,” the Marine told an industry audience at an AFCEA event.
