On the flip side I have taken command of CVs from the other side of the map by request. I had the rank, the previous CO was doing a poor job and ticking his local friendlies off . I would follow up by moving local to the TG, or finding someone local who is competent to take it over. I've also been in flight observing the map and saw something stupid being done with the TG and pulled rank. Had I been required to exit flight, move to the TG and take command it probably would have already been dead by the time I could take it.
On the rare occation where I have finished a tour with a good rank, it was because I disagreed with TG command at some point, and did my score chores so that I could pull rank the very next day. My opinion has always been that there is already a game mechanic to address disagreements over TG command. Outrank the current commander, or have a friend who does.
