I’m sure I’ll get much blowback on this, but this sort of thing is a bad idea, period. ..
Military units should be independent, no matter where they go or what they are doing. Relying on a baggage train of civilians for basic functions is just asking for trouble.
Unit cohesion is based on everyone being able to gripe about the same duties that everyone does. If everyone gets KP and Latrine Detail occasionally, then, it is just another experience that they have in common; and, (significantly), another ongoing opportunity for NCO’s to demonstrate leadership.
Everyone is a rifleman. And washes dishes occasionally.
The Roman Legion operated this way, and look what they accomplished. (That is, before they started relying on auxiliary troops.)
Sorry SOF’s. Elite doesn’t mean that you’re exempt from basic ongoing military tasks.
The US military hasn’t done much Kitchen Police (KP) since at least the 1970s, with a few exceptions here and there. They have civilians for that, both stateside and overseas, except for naval vessels. The South Koreans have a mix of enlisted soldiers, hired civilians (mostly motherly middle-aged ladies) and volunteer mothers who keep an eye on everything.
