Sacrifice of Soldiers
杀士者，非恶之也，所以利战也。
Disciplining soldiers is not malice, but for the benefit of victory.
明赏重罚，爱兵如子，同甘共苦，激气励士，士乐死战。
杀士者，非恶之也，所以利战也。
明确奖赏、严厉惩罚，爱护士兵如同自己的孩子，与士兵同甘共苦，激发士气鼓励战士，士兵就乐于拼死作战。严格治军不是出于恶意，而是为了有利于作战胜利。
Clear rewards, strict punishments, care for soldiers like family, share weal and woe, inspire morale, make soldiers willing to fight to death. Disciplining soldiers is not malice, but for the benefit of victory.
治军需恩威并施：严纪律、明赏罚、爱士卒、激士气
Command with mercy and authority; strict discipline + care = invincible army.
"杀士"之"杀"非杀戮，而是"减杀"——约束、磨炼之意。孙膑的治军哲学是"恩威二元论"：既要"爱兵如子"，又要"明赏重罚"。这种张力与现代组织管理中的"高关怀+高要求"领导模型完全一致。
Compare to "servant leadership" (Robert Greenleaf) + "extreme ownership" (Jocko Willink). Compare to Sparta's agoge training system.

Wu Qi personally sucked pus from a soldier's wound. The soldier's mother wept: "His father also served thus and fought to the death" — a model of combining mercy with authority.
