Fast Mag- Kill within 5 seconds of reloading

???
Tactician- Kill with 2 different tactical
Danger Close- Kill with a class with two lethals
and some of the sight challenges don't work like bloodthirsty, longshot, scarerow on certain guns just like with rapid fire.
Edit: Some of these might work without the uav on like Dead silence and Awareness.
good finds. i was hoping someone would have found something out by now on how to complete these challenges.
