提　　要 各項軍事行動的發動，如何在進行中，有效管制武裝力量，目前大都以「交戰規則」作為最重要的規範之一。美軍交戰規則是以「任務完成及自我防衛」兩大概念為中心，即使在賦予危急任務時，也都不限制自我防衛的最後底線。而國際人道法學院交戰規則的地面軍事行動，須先要思考行動發生在自己的主權領土上及他國的主權政府管轄，且要符合法律依據，如「駐軍地位協定(SOFA)」、「備忘錄(MOU)」或其他國際條約等國際法。 地面軍事行動是戰爭活動中，最直接面對敵我雙方交戰的場景，其所涉及法律議題，也最複雜，如武力使用的強度、自衛權的界線、武裝衝突附隨的損害等等，所以，國軍應該充分地學習國際交戰規則的運用，以及強化多國聯盟軍事行動的合作，期可增添「依法用兵」的建軍價值。
