I do not think it would be un -feasable.How many people travel on private airlines around the world a day? I do not know but its alot
There are private airlines, who could fly hundreds of thousands of troops to the Middle east.Esepecilally in this economic climate....im sure there would be a large number of Airlines who would love to lease there surplus aircraft to the USA.
As Marc1 has stated the Australian Defence Force uses a lease arangement with an A-330.
Also some of the The Equipment and manpower of the USA are located in bases in Japan,turkey,Mid east ect.They pre deployed form those bases.
Heavy equipment like MBT are sent by ship..that is a fact.
GW2 i can remember Aussie clerance divers,clearing a port of mines so heavy transport ships,LHD could dock and unload there equipment.
All in all a massive logistics task,it would be nice to hear from some senior members on this topic to clarify how the USA deploys its troops.
thanx
