Even on hard there's a fairly easy method to completing this map using quick save/load (anyone who claims to have completed this map first go on hard is a liar).

Each time you get to a part you're stuck on (can't locate the hidden sniper, or your men keep dying to him) run out ahead like a madman and let the snipers shoot you.

Don't focus on trying to see them, just let them hit you and watch the compass. This will show you which direction you are being hit from. Reload and try again this time looking in the direction you got shot from and you should have no difficulty locating the snipers.

Once you know where they are you then need to prioritise which to shoot first and then it's all up to practice and skill.

This is the layman's method. You don't have to run out like a fool, you can try your best to feel through the map bit-by-bit, but the same rule applies.

When you get hit, look at the compass.
