Sea Change?
It seems that the civilian leadership at least thinks so. With Naval/Marine officers in the CJCS VCJCS, and in several high profile Unified Commands, the Navy/Marine Corps seem to be running the show for the time being.
Sure does look like a sea change (no pun intended) with "Naval" services getting the majority of 9 Combatant Commands after being minority for quite some time
PACOM - ADM Keating (second COCOM)
CENTCOM - ADM Fallon (second COCOM and 4th four star assignment)
SOUTHCOM - ADM Stavridis (youngest 4 star on the block;
watch this guy for where he goes next)
SOCOM - ADM Olsen (first SEAL 4 star)
NORTHCOM - GEN Cartwright (next Vice?)
Interesting that Marines have been moving more and more into 4 star billets never available to them in past decade (they have now served as CJCS, VCJCS, EUCOM, CENTCOM, SOUTHCOM, JFCOM, and STRATCOM). Likewise, Admirals have also been moving into COCOM assignments traditionally held by other services as of late (SOUTHCOM, NORTHCOM, SOCOM, and CENTCOM)
