There have only been four Cowboy Ones since they reactivated the squadron for The War.  We normally don’t change numbers.  I will always be Cowboy Five, and there will never be another Cowboy Five.  But there will always be a commander, a Cowboy One.  The Colonel died as One.  Charles and Christian survived to retire.  I actually never served with the current commander, but I’m told he’s a good One.  Of course, he’d have to be to get Aneerin’s support.
