NATO’s plan to vastly increase its forward force is wishful thinking, and the UK’s struggle for military relevance is a perfect case in point by Scott Ritter

Given what we now know about the reality of modern warfare, courtesy of the ongoing Russian operation in Ukraine, the British battlegroup would have a life expectancy on an actual European battlefield of less than a week. So, too, would its allies in the Estonian 2nd Infantry Brigade. First and foremost, the units lack any sustainability, both in terms of personnel and equipment losses that could be anticipated if subjected to combat, or the basic logistical support necessary to shoot, move, or communicate on the modern battlefield. Artillery is the king of battle, and the British and Estonians are lacking when it comes to generating anywhere near enough tubes to counter the overwhelming fire support expected to be generated by any hostile Russian force.
