Hmm. I'm not military, but I'll take a swing at this one.
How about a lighter tracked infantry fighting vehicle with a companion tracked fire support vehicle? The M1/M2 combination is arguably the best combination of heavy armor in the world, but deploying any sizable amount to any given spot around the world in less than three weeks is almost impossible. You
can airfreight them by C5 or C17, one M1 or 2 M2's at a time, but doing so wrecks runways and stresses airframes. They are also enormous fuel hogs.
For an IFV, I'm thinking of an MTVL (an up-engined stretched M113A3) with a small turret or external weapons station fitted with a light 30mm cannon (M230LF), a M240 machine gun and possibly a weapons mount for a pair of Javelin missiles. Alternately, the MTVL can be fitted with every weapon system that can be fitted to the M113 (there are quite a lot
).
For the fire support vehicle, sometimes also called light tank, I'm thinking of the M8 Armored Gun System. It is a 3 man light tracked vehicle mounting an autoloading 105mm gun and a M240 MG. It was tested, accepted and type-classified before not being fielded for political reasons. If introduced, the 82nd and 101st divisions would probably have fistfights over the rights to the first units to have them.
Both of these vehicles can be transported by a C130 in battleready state and can also be delivered with LAPES or conventional parachute drop. Both can also be fitted with extra armor to withstand cannon fire and RPG warheads.
Yes, I know the US Army is busy trying to field the Stryker Interim Armored Vehicle. Unfortunately it is wheeled
1, apparently underarmored, underarmed and is too big and heavy for a C130 to carry it any distance a in battleready state, though I'll admit you can load one on a C130 after stripping off parts. To make things more interesting, the Mobile Gun variant is to tall to fit in a C130 under any circumstances. A more indepth look at the Stryker, and why it should
not be fielded is
here.

1) Wheeled vehicles have far higher ground pressure and, if all wheel drive, far more complex drivetrains than tracked vehicles. Wheeled vehicles get bogged down a lot more easily than tracked vehicles of the same weight. Also, unlike tracked vehicles, they cannot pivot (yet). Imagine yourself on a mountain road surrounded by cliffs when a sudden need to reverse crops up (bridge or tunnel out, for instance). The tracked vehicle pivots on its own axis but the wheeled vehicle will probably have to be reversed down the road.
