A lot of that is that losing your forces due to non-combat accidents can hurt your mission. In addition to broad authority to regulate lives, they're given responsibility for accomplishing a mission; that doesn't really exist in the wider world (what is the "mission" of the USA, or really any country, w.r.t. its citizens? This becomes a philosophical debate rapidly.) IIRC, more junior enlisted Marines were dying from motorcycle accidents, per capita, back at their home bases (it might have been specific to San Diego), than in combat in Fallujah. (OTOH, they went overboard with things like the PT belts...)
