Look at it this way: not counting Generals Galvin and Joulwan, being CINCSOUTH was generally a pre-retirement command.... Where does he go next?[/QUOTE]
How many 4 star billets are there? How do you laterally promote a General when most of the billets are for 3-4 years and you still have to promote the younger year groups? Would you like to go from a 4-star Command to a staff job (I can only think of ACJCS and the Asst Chief of staffs)? Granted there some CINC jobs that are politically better than others like SACUER.
I think almost any CINC job is the last step (highest step on the ladder) w/ no where to go but retirement and a career in TV or politics.
