Communications between units, their command and other services is vital - but was ignored for decades.
Army units used Korean War vintage radios through the ‘70’s and well into the '80's.
As some on here know I was in our Army’s navy. We would conduct JLOTS operations with Navy forces every year. Every year we would write up a Lessons Learned about the near impossibility of Army vessels communicating with Navy vessels without using our civilian marine radios. Signal flags were woefully inadequate - and only worked if the wind was blowing the right direction. Blinker light was slow and depended on visibility and distance.
I’m glad some one finally woke up.

Blue Force Tracking gains ground

"I never used another paper map product for the rest of the war and fought every fight thereafter using Blue Force Tracking," [Lt. Col. John] Charlton [commander of 1-15 Infantry, 3rd Infantry Division] said.

I used to run a tank battalion TOC. Seems like technology has changed so much that for me to try and function in a TOC now would be like a gunner's mate on the Monitor trying to fire phasers on the Starship Enterprise

Maybe that kind of stuff will finally fade away as the Department of Defense gets purpler

I recall reading in "The March Up" at the end of the drive to Baghdad units of both the Army and Marines were in Baghdad on opposite sides of the Tigris river, they could see each other but they couldn't communicate to each other. So we still have a ways to go with "jointness".

That was me. Sitting at ranges at Ft. Bragg, looking at the vehicle I wanted to contact, but getting only Cuban fishing boats. Half the time we used our own purchased Motorola's.
