As for me i did mine on the 2nd Mission "recovery" when i was going for the 2nd secondary mission on that level. Just try to stay in the bushes and foilage and try to take out enemies with headshots, and if they're 2 people next to eachother then kill them in quick succession then it still counts as long as they don't see you.
There is only one secondary objective on "Recovery"
Isnīt there any good spot? Donīt you need a weapong with atleast an assault scope or sniper scope?
