It's letting just about anyone in the Army offer up their opinions and contributions to Army doctrine.
The idea is to get more first-hand, battle-tested knowledge from the soldiers who have been on the front lines and had to practice Army doctrine. Those soldiers might have better ideas of how to improve or more efficient and effective ways of doing things.
The Army has been piloting the idea for a few months and seems okay with some loss of control. Perhaps they're buying into the idea that collaboration makes for better, or more creative ideas and sometimes stronger policies. But, the whole thing could go wildly out of control.
Despite potential downfalls, the project is supported from the top.
