Just sticking to the modern CINC era (and acknowledging that they aren't called CINCs anymore), it seems that rather than being a career-ender, SOUTHCOM is practically the only one with a future.
Since Goldwater-Nichols, three SOUTHCOM commanders have become SACEUR - Galvin, Joulwan and Clark - and one - Pace - became Vice Chairman of the JCS.
All CENTCOM commanders have gone into retirement after their tour in Tampa.
Pacific Command has mostly led to retirement:
- ADM William Crowe - CJCS
- ADM Ronald J. Hays - retired
- ADM Huntington Hardisty - retired
- ADM Charles R. Larson - Superintendent, USNA
- ADM Richard C. Macke - retired
- ADM Joseph W. Prueher - retired (then Ambassador to the PRC)
- ADM Dennis C. Blair - retired
- ADM Thomas B. Fargo - retired
Atlantic Command, later Joint Forces Command, has also mostly led to retirement:
- ADM Wesley L. McDonald - retired
- ADM Lee Baggett, Jr. - retired
- ADM Frank B. Kelso II - CNO
- ADM Leon A. Edney - retired
- ADM Paul D. Miller - retired
- GEN John J. Sheehan - retired
- ADM Harold W. Gehman, Jr. - retired
- GEN William F. Kernan - retired
- ADM Giambastiani - VCJCS (designate)
European Command is also SACEUR and is usually a second command. It should be noted that Atlantic Command was also SACLANT, and some of the admirals above had previous 4-star assignments.
Generally, it's the same for the thematic commands as for the regional commands. All USSOCOM commanders went into retirement except GEN Shelton (while GEN Schoomaker was recalled to active duty). GEN Fogleman is the only TRANSCOM commander I know of to have a follow-on assignment, and the same goes for GEN Myers and SPACECOM.
