Multi-Domain Command and Control (MDC2).

From a previous blog entry the question as asked: "Details of this latest modernization not given but said to include and to concentrate on multi-domain warfare. Whatever that includes."

Multi-domain warfare!

From the Internet web site War on the Rocks and for the perusal of the devoted reader to the blog info on multi-domain warfare.

"MULTI-DOMAIN BATTLE: AIRLAND BATTLE, ONCE MORE, WITH FEELING"

"So, what is this Multi-Domain Battle that everyone seems to be talking about? Is it a brave new concept that will carry the day and the Army to a revolution in military affairs? Or is it just AirLand Battle with a dose of cyber?"

See also additional web sites with an index or various articles the topic of which is multi-domain warfare:

Personally I do not understand and do not pretend to know so.
