CoD4 on Veteran = Me pulling my hair out

ok so ive gotten through the first act fine but now im at one shot, one kill where you have to snipe about 1000 dudes and its ridiculous. this was the hardest part of the game for me on hardened too though so.... any suggestions?

btw CoD4 is awesome which is why i feel the need to beat it on veteran...oh yea the MP is not too shabby either

I only just beat the level on hardened this morning. I was playing a couple of days ago and kept dying. Tried it this morning and finished it 2nd try.

Now I have to try Veteran too. :(
Thanks for the youtube video ascendentjustic, should help a lot.

its not hard

i just need to find 2 more intels before i get the full 1k
