My experience is that many of the older COs feel trapped and are getting tired...I have seen 4 leave to take care of "older parents," parents that had needed help for some time and were being taken care of by others...bad health is another reason they leave.
The COs have to be company men even more than the elders...they are financially more dependent on the WTS and there next assignment depends on how "nice" they are. Don't want to be sent to the cold northern climes of Minnesota or Wisconsin.
