re:
Overseas Assignments & Restructing
In the Army's case almost all of the tours to Korea, and a lot to Germany are unaccompanied tours ie no spouse, kids, etc. The amount of household goods a single soldier can ship is also limited.
Command sponsored tours ie with families are rare in Korea, I think due to nature of being so close to N. Korea, and past history of being overrun so quickly.
Having all units within American borders is not necessarily a good thing. Remember how long it took to get all the troops into Saudi, during the '91 Sand Shoot? Granted the 82nd Airborne Div and 18 Airborne Corps deployed immediately. However they lack the combat firepower to hold an area by themselves. Having the ability to pull Armored and Mechanized units from an area such as Germany to reinforce them makes more sense than to try pull a heavy unit from the states.
Granted to US now has equipment prepositioned
at various location throughout the world, such that a stateside unit could muster its troops and deploy carrying only their personal equipment.
Also consider that since the end of Desert Storm, the military has been downsized so that many of the traditional overseas assignments no longer exist, The Berlin Brigade comes instantly to mind. Several divisional sized formations were inactivated in Germany alone. So in essence the military has been restructed.
The problem is that we don't have an "ENEMY" anymore. Sure there are the constant brush fire wars ie Kosovo, Bosnia, and Somolia, but the large Soviet threat no longer exists.
I read recently where the Army is looking to streamline its forces along the lines of the Marine Corps and IMHO loose a majority of its heavy assets, for more perceived mobility and flexibility.
So there are always pros and cons of any restructoring.
