You know who it is. The one you somehow managed to leave off the list and baiting people to 'specify'.
Consult this if you're referring to the USAF. Our contingent in Asia isn't that large or impressive, unless you count Guam and Hawaii in Asia too, but these are the units stationed in Asian nations.

If we take into account all US aviation units, from the USAF, USN and USMC, than our contingent would be overwhelmingly large and dangerous, but taken alone, our Air Force isn't that impressive in Asia.
And given the large distance from the US mainland to its overseas bases and stations, replenishment times are large too. The US faces a logistics problem in Asia due to the vast distances it must cover, but it makes up for this pit-fall through superior training, practical experience, trans-national support and technology superiority.
Our force is impressive, but taken alone, the USAF has problems. The USAF and USN always act in conjunction, both on offense, defense, support and logistics to ensure both services can accomplish their missions. The USMC also supports their operations.
The USAF is strong, very strong, but it does face downward pressures that can be its undoing.
