Don't listen to that Claudia freak!
When you come in on the truck kill the soldiers and walk forwards into a room where you will see a crate, I think you need to move it and jump/climb to the higher platform.

Well, not the Soldiers you see while 'standing'.Hop off truck immediatly, then hideout,nab treasure and 'pick-off' Communists as you encounter them..eventually, you'll be left at room with TNT behind a Locked Door.When you turn around,a CIA guy will arrive & talk to you & give you the KEY, He exits and you must fight off a couple Communists, then 'blowup' TNT room (at safe distance-of course..you'll see your EXIT-hole, heh heh)
