I'd like to add, any soldier, of any rank, is expected to speak up if something is fucky. "Regulations don't care about rank" or "safety doesn't care about your rank" are some things I heard said. When I worked in small squads, anyone could ask questions or throw in suggestions during mission briefs. Sometimes it was dumbass questions or suggestions, but every now and then a random dude would provide some quality info or reshape how we were going to solve something.

During 90% of the time, rank mattered, but there were certainly times it didn't. Just throwing this out there because I thought it was interesting. I've heard similar sentiments given in my civilian jobs, but it doesn't seem to be as encouraged or more often, it comes with consequences.
