Combining the carrier battle groups and amphibious groups at sea involved in these two exercises, there would be enough seapower to invade practically any country on Earth.
30,000 troops isnt a lot of personnel for a large scale invasion. Maybe a first wave of assault troops, but thats about it. Its a little more than one division.
This reminds me a lot of the old REFORGER and RIMPAC exercises of the Cold War era.
