Found the missing qualifier for you.
When an order is 'clearly' against the conscience of a soldier, e.g., shoot civilians, that shoulder should be held accountable for his actions. There are scenarios when underlings are asked to carry out orders that he does not see or understand as being illegal. Underlings are not military legal experts particularly when it comes to gray areas like enforcing Covid protocol. The ones that should be investigated are those in the know like Biden's team, the pharmacutical companies, Fauci, the NIH etc. When will the heads of the snake be investigated and prosecuted. Until that happens it's just kabuki theater.
