《孙膑兵法·篡卒》
军需充足在于作战时能够速战速决减少损耗，军队的强大在于能够合理妥善地休养生息养精蓄锐，军中士气削弱，明显的损伤过大，则在于太过频繁的征讨作战。 
孙子曰：德行者，兵之厚积也。信者，兵明赏也。
Sufficient military supplies lie in the ability to fight quickly and reduce losses during combat, the strength of the army lies in the ability to rest and recuperate properly and conserve energy, and the weakening of morale in the army, obvious damage is due to too frequent military campaigns.
