For those that got it what level did you do it on? I'm going through my vetran game right no (about halfway) But i figure i'll go back and do that since its one of the few i have left.

Finally got it, i've been trying to beat veteran for a while and finally finished today.

got the close combat on the night drop level. It was pretty easy on easy and i went to the flack guns first. Didn't even die once, what a change from veteran where i did the last checkpoint about 30 times.
