Soldiers and many police perform small unit tactics. Civilians in a self defence situation do not. This is the key motivater behind weapon choice.
Whereas you leave uatended firearms around your home, if a soldier did this around the barracks he would be court-martled.
I'm of the firm opinion that leaving guns laying around, even if hidden, is grose negligence and should never ever be don. The firearm should either be on your person or unloaded and locked away.
