Having carried the bastard's radio and driven his jeep, (before you were born) I can state with absolute certainty that in U.S. Army, Back In The Day, all field officer ranks were expected to inhabit foxholes. They are not (and were not) called foxholes, they were called "positions". They haven't been foxholes since Korea. But I digress.
However, we dug them for said officers.
There is the chain, and there is everyone else. If you're in the chain, and you're not in a position, you're asking for a frag.
No one cares where anyone else is, there's a reason they're not in the chain.
