How long Britain could really fight for if war broke out tomorrow

There remains little evidence that the UK has a plan to fight a war lasting more than a few weeks," argues Rusi's Hamish Mundell. "Medical capacity is limited. Reserve regeneration pipelines are slow… The British plan for mass casualty outcomes appears to be based on not taking casualties." With classic British understatement, he says: "This could be considered an optimistic planning assumption." He adds that to fight a long war you need proper back-up. "It demands a second and even third echelon; personnel, platforms and logistics chains that can absorb losses and continue the fight. Yet this depth is notably absent from current British force design."
