Sorry, but M-60 tank is also way too heavy. Here is a page with info on the C-130. http://www.fas.org/man/dod-101/sys/ac/c-130.htm About all the standard C-130 can carry is 45,000 lbs, 22.5 tons. As I said before, an M113 or an M551 Sheridan is about the heaviest vehicle they can carry.
As for the AH-6, it is a light attack helicopter used by US Army Special Ops troops.
Here are a couple in 1/48 scale:
With the blades folded, a C-130 can carrry two AH-6s.
Another option is to load 1 OH-58C helicopter in the Herc.
Here are couple of OH-58C in 1/48, first one is by Italeri:
They should be easy to get in 1/48 scale too.
