“Forget the tank, the fighter jet and even the drone. Artillery is the most important weapon on the modern battlefield, just as it was 100, 200 or even 300 years ago. It was not for nothing that Stalin dubbed artillery the ‘God of War’.
So it’s extremely problematic that the world’s leading army, the US Army, can’t manage to develop a new howitzer. Trying and failing three times in a generation to acquire new heavy artillery, the Army is stuck with upgraded versions of the same howitzers it’s been using for 61 years.”
