manitou: You failed to address the parallel that American_Yerushalmi provided you comparing it to the intelligence officers who work in offices behind computers and never enter any foxholes or front lines. Or, to use another example, the mechanics who fix the army jeeps; they too don’t fight as soldiers.
So too the Yeshivaleit who work in the Beis Medrash defending Jews all over. Like the intelligence unit, they too never wear the army fatigues.
