You know, if Trump wasn't a candidate for president, I wouldn't really care about what he says.
However................if you're going to be CIC, you should at least watch a bit and see what is going on in the ME before shooting off your mouth.
Talking like that might undermine your authority with the troops, because they won't trust you. Yeah, they will still do their job, but they might not do it as well as they would if their morale was good.
Talking bad or treating those under your command in a bad way never works out well for those in command. I've seen what a shitty captain can do to a perfectly good command and it's not pretty.
