Nemesis-ZA

playing this on hardcore I cannot get a perfect mission. I get an A with marksman/man of steel/leader/black ops - accuracy 100% 42/42 instant kills. the problem seems to be stealth which I cannot get over 90%. It seems to be the enemies around the silo and truck in the middle of the quarry. the minute they spawn they start running around. I have run this with a MP5SD, single shot kills without any enemy having a chance to react. where the hell am I going wrong?
