This was a hallmark of the Citizen Soldier Armies of draftees and Guardsmen the US fought pervious wars with as well - but it is a commodity discouraged and feared by the highly starched, doctrine driven regular force who serve to stay and make careers rather than to fight wars and go home.

One more reason to keep the regular force small in peace and to expand with citizen soldiers to fight wars when necessary. A luxury the US has due to our tremendous geo-strategic advantage over smaller countries that enemies can simply drive or walk to. Sure, we stumbled in a first battle or two, but it is last battles that count.

We are losing this within SOF as well as SOF is now part of that system of careful career over carefree service. Probably still alive down on the teams, but not as one moves much upward from there.
