OK, here's my attempt at the E&E walkthrough:

to get to Obj. A you must go on the right path, but stick to the left side of it, when you are almost to the enemy camp you should see a path that leads over the hill, lowcrawl up this path and over the hill to A.

for obj B, gett in the ravine and go right, stick on the rightmost path, but hug the left bank to avoid detection (remember that if an enemy yells you must drop to prone, hopefully you're already in prone, and wait until they say "Ni")

For C you have to get past a spotlight, I found it helpful to crouch-walk into the crevice between rocks, let it pass to the area you came from, then stand-walk to clear the spotlight's area of "patrol" and go back to crouch. Next you will take the right path and crawl into the ravine (don't even try the bridge, it's futile), go to the right end of ravine and crawl out, avoid the last guard (move only when he faces away) and signal with truck.
