I know it sucks to hear but sadly it is the truth. To use a more recent example Wozniak from Apple did all the work but always stayed in the relative limelight and he actually gave money to the people who helped in succeed. The successful leaders all depend on many loyal followers.
Even in the revered Band of Brothers TV Series (which I still think is good) there was a lot of politicking and also apparently antisemitism going around. My main source here is Ed Shames Lt. 101st who I had some discussions with IRL. Also in the US there was a lot of antisemitism in the 30s and 40s according to Ed Shames. Well the Klan was still really big back then. So politicking is everywhere, then again humans have short lives and more often then healthy for us very large ambitions. Also just writing about “the greatest generation” while ignoring the negatives sells more books.
Maybe also to press the point, we historians sometimes not realize this as writing books/papers or just this post is a fairly solitary activity and requires a lot of thinking over decisions. As opposed to military leaders who have to make decisions quickly with limited and continuously changing information. Also they must have, not sure how to put it best in writing, a certain casualness about losing people under their command.
This is a very different mindset than spending hours evaluating and not having to worry how many people died because of your decisions. Also they could die any minute themselves in WW2.
Everyone was under massive pressure and leaders within large organisations often are to very uncertain people on the inside who above all are scared to lose their job or secondly as a result also go down in history as another “loser”.
