I am unsure about the community, but at least within the 42nd we have got rid of 2 regimental leaders. Jimmy and Genital (both before my time). I don't know which did what, but one used team speak to listen on others conversations while in another channel, and would join if his name was at all mentioned. Plus both were complete control freaks and arseholes, who did not treat the members of the regiment well. So both were kicked out in our first 6 months. (there is more I just don't know it all, as it happened before I joined the reg).
I wouldn't class this as betrayal as they both deserved it. But it depends on what way you look at it from.
