To explain this, he borrowed a famous line from Shakespeare's play Henry V which described the phenomenon called the "band of brothers effect." That is the essential glue in military culture that causes a young man to sacrifice his life willingly so that his buddies might survive. We know that time together allows effective pairings, or "battle buddies." Four solid buddy pairings led by a sergeant make a nine-man, battle-ready squad. General Scales says that veteran SEALs, special forces, Rangers, tankers and line infantrymen will swear that the deliberate, premeditated and brutal act of intimate killing the enemy is a male-only occupation, and they know this intuitively from battlefield experience.
Generations of our ground-force leaders are united in believing that the precious and indefinable "band of brothers" effect would be fatally broken with we were to force mixed-gender infantry squads. They know another thing, too: changing this practice is not a decision that should be made by judges.
