To be honest, internal competitiveness is the unavoidable result of when you have an organization of people and you label one part "elite" and the rest "normal". Naturally those who are labeled "normal" feel the desire to compete with the "elite" to prove themselves good enough to be elite or what have you. I'm not saying it was designed to be that way, or that it should be that way, but it's the unintended side effect when you essentially label one section of people within your group as 'better'. That was one problem I noticed in Erebus in regards to it's elite unit, Death. People who were not apart of Death generally viewed Death negatively and always tried to outshine them and compete with them lol. I'm not saying that you need to do away with Elite Units or what not, just that a degree of internal competitiveness is generally unavoidable when you label some people as such. You can spout real-world military examples of how that doesn't happen but really that'd be incorrect and you'd have to stop and take a step-back and realize that this isn't a real life military and that at the end of the day, we're all just playing a video game. Video Games by their own nature are competitive and while it might seem dumb for people to compete within their own organization, it happens. Just like you have people in the United States Military that go "SUCH AND SUCH BRANCH IS BETTER THAN SUCH AND SUCH BRANCH." That's my opinion, anyways. I personally don't feel the need to compete with the "Elite" squads but I'm just offering up a perspective as to how the internal competitiveness can come to rise. We might be one big happy family, but that doesn't mean people don't want to try and show each other up. Imagine it like this. You're apart of a big family, you're all happy, but than your father proclaims your oldest sibling is his favorite or implies in any other way that said sibling is better than you. Sure, you all work toward the same goal, but you also end up wanting to prove that such-and-such sibling is not better than you. tl;dr Internal competition generally comes along with "You're elite" and "You're normal".
