As a young Cpl on the Harrier Force many moons ago, I read the book whilst on nights in Syscon at FWOC. At endex, in true bluejob tradition we had a barbie(!) I ended up chatting with the Force Commander, Gp Capt "Dickie" Johns. I asked him if he had read the book as in the chapter entitled "The Air War in Central Europe" It mentioned the Harrier Force. The book being written by General Sir John Hackett and Others. He informed me that he had actually wrote that chapter. He was one of the "others" How spooky that I asked a man if he'd read a book only to find that he'd written part of it!
First Clash by Kenneth Macksey. Good read. Third World War, excellent, Team Yankee okay imho. Bit too easy for 105mm armed Abrahms to defeat T72's and T80's in my view. IIRC they also mentioned using the FIST vehicles.
I thought it kicked off over the Russian harvest failing once too often. But it's been a long time since I last read it (even longer since the first time - about 1978, first run hot off the press with about the first 60 pages printed twice due to a publishing error).
If you liked Hackett's book (and I did), you might also find this one interesting. It is the same sort of idea but based around a war kicked off by China attempting to re-take Taiwan. A bit more up-to-date than NATO vs. Warsaw Pact.
