Quoted: The heirarchy of transport aircraft size:
Our 2nd largest is the C-141.
Our largest is the C-5.
Our C-17...well, I'm not sure. It's in the C-141's size range, anyway.
The 2nd largest Soviet plane is the Antonov AN-125. It is slightly larger than our C-5.
The largest of all is the Antonov AN-225. It's CONSIDERABLY larger than the AN-125.
The IL-76 isn't even in the running.

C-141: Max Payolad: 70,000 lbs (unless they've restricted them more since I stopped working with them).
C-17: Max Payload (pre-block 12): 170,000 lbs.
A general comparison is that a C-17 can carry outsized loads like a C-5 (although the C-5 has higher capacity), can land on austere, semi-prepared fields like a C-130, and takes up as much room on the ground as a C-141. A maxed out C-17, at 585,000 pounds gross weight, can land and takeoff using 3,000 feet of real estate. Plus, reliability rates are consistently in the high 90s.
That picture with the two main landing gear shows integral jacking. You don't use an axle jack to change a tire. You put a lock on the gear with the bad tire or brake to keep its shock absorber from extending, then run a hose from the No. 2 hydraulic system (4,000 psi) to the bottom of the shock absorber of the other gear on that side, using that gear to lift the other off the ground.
Cool stuff.
