Does the Military make it too difficult to get rid of bad Service Members?

One of the things that needs to be remembered here is that once the Army separates someone, that has a lasting effect on that individual, and possibly for a family also. I mention that for two reasons. One, it is a process and it can be a lengthy one depending on the circumstances. I believe that is designed to ensure that everything is done correctly and also that all avenues of rehabilitation were explored and exhausted. Two, depending on the type of separation, there may still be some benefits that may require additional time to complete prior to separation (ie ACAP). Granted on a case by case basis, there may be roadblocks as you call then SGT Cotton. I believe though that the system is designed to ensure the Army gets it right.

Yes. And its making it too difficult to KEEP the good ones

Certainly your example of a bad NCO is an example of this, but I believe we in any branch are a special situation. We retrain and punish within first, then pursue discharge if there is no other course of action. I have had a few soldiers who seemed hopeless that turned into fine NCO's later! I'm glad we didn't give up, even if it seemed "easier" or the "best" choice at the time! Also, I made a fairly big "mistake" once and was almost booted (1995, during drawdown no less). My command didn't choose that path, and I was able to become a good sergeant and serve later in combat! It's a tough call folks but that's the job!
