Technically, soldiers absolutely are (legally) required to question authority in some cases (e.g. if they think an order is immoral, like participating in a genocide or murdering civilians or torture). In practice it provides more utility to stomp out any desire to challenge or question authority though because if a soldier spends time critically thinking about an order they're given, that's time they're not spending being highly alert or implementing that order.
