Ammunitionwas stockpiled only for one-third of the divisions and even that would lastthem only fourteen combat days. Requirements for another fourteen combat dayscould be covered by reserve stockpiles but that would be the end. The Air Forcewas in a similar situation—after about fourteen combat days, the pilots wouldhave used up their bomb supplies and could then “go play cards,” as the AirForce inspector general, urgently warned Chancellor.
上面句子中的“would haveused up”应该理解为过去以后完成时，而不是表示过去的虚拟语气，如此的理解是不是正确？
期望老师解惑，谢谢！

是的，网友理解正确。前面时间状语 after about fourteen combat days，说明 “经过约14天的战斗之后”，表示以后时间，飞行员们将会用完他们的炸弹补给。当然，过去以后完成时中 would 带有推断的成分。
