That's worrying...
"you must follow legal orders" does not imply "you must refuse illegal orders"
Without a broader reading this section implies that obeying illegal orders is optional... which also implies it'll be on the service member to prove the order they disobeyed was illegal, at their court martial. Which puts a lot of pressure on them to do what they're told, they have to be really certain the order is illegal 🫤
Are they any better behaved?
