No command and Control??? Hmmm, guess that depends on who their "Friends" are..
But I agree in general about the massed Armored Attack.. Not likely..
The speculation of massed armoured attacks is a moot point. You can keep every Challenger, Abrams, Leclerc, Leopard and T-90 back at their ramps and parked in neat little rows with the turrets turned and locked. Simply because they exist, the A-10 and the Su-25 have a reason for being.
Just like the ram bow that was still present in 1941 on several classes of American dreadnoughts, the 21st Century world is very reluctant to release it's 60 ton battlefield monsters to the pages of history because of tradition and the status symbol they represent for the leadership that still remembers the Cold War and the what-if scenarios so vividly portrayed by Tom Clancy and Harold Coyle.
Will they eventually go the way of the Dodo? Perhaps. In our time no two democracies have ever gone to war with one another so the need for heavy armoured battalions may eventually run its course. However, today and here and now we are still in a transition era where the sight of a column of main battle tanks is still impressive enough to earn their keep.
