Found a bug. In the second Kosovo mission right after you turn on night vision, if you switch to the pistol the controls lock up and you just have to wait for the guy to kill you.
I'm not. I'm loading my save on hard mode level 10, where it just starts with two cormorants. I kill them both without using anything but my gun, and then die to the next wave. Did it twice, no badge.
Anyone else failing to get the Jackal badge? Is there some other requirement like "win the level?" Unfortunately, it's not something I can show with a screenshot so the normal method of getting missing badges won't work :(
