Dmitri does that dad stare a lot... I'm not comfy with it, but he says as long as I don't hurt anyone, I'm safe.
Boris... Boris is a good person, he does many questionable things, but he is a fine soldier.
Ivan... Now, He may be my brother in battle, but he is clearly not my brother in intellect, as I have convinced him that all these stupid ideas can work.
Boris has so many unique tactics, we can use them so much, why doesn't Dmitri try any of them?
