The point is technology and innovation have advanced far past what DCGS is capable of doing. It's not an agile enough tool to be able to incorporate and integrate the most advanced technology that is on the shelf today that can be bought by our forces that frankly our war-fighting units want.
DCGS is hard to learn. It takes a long time. You have to use it all the time, which means it's not a simple technology that people are used to and can buy off the shelf today. And frankly, it doesn't do what it's touted to do. That's why you see units out on the battlefield asking for very similar things.
