I'm talking generalities here, but it seems like certain immature cadets view leadership as putting themselves ahead of others, bragging, and putting on a show, constantly talk about themselves with TMI etc. Their main purpose is self serving, to be the best at all costs, and to make sure everyone knows they are better. There are other cadets that are modest that are in fact better than these individuals, and are good positive leaders. They positively influence those around them, develop and motivate others etc. Unfortunately, those individuals in the former category get encouragement from cadre (I'm not criticizing cadre, they probably don't see this) further ingraining their toxic behavior. They tend to be teacher's pets with the cadre, whom don't necessarily see that side of their behavior. If this is their behavior in ROTC, it is likely to translate to their career as an officer and difficult to reverse. Individuals such as this typically end up on top, and anyone that interferes have little to gain. If someone told him to tone it down, he would probably just tell them to shut up or cast them as being jealous. Perhaps this can just be chalked up to lack of maturity, but plenty of people never grow out of it. What is the solution? Also, to be clear, there is nothing wrong with excelling and working hard to be the best at something. It is just the way one goes about doing it and the intention.
