I have a few sweet kills. one was when me and my friend were playing in highrise, and we were both in seperate buildings. i was aiming at him through my barret and he ran behind some blinds hiding him from view. i took a shot and got him in the head.
also when i was playing in estate. Me and some of my team were in the main room of the house, and this dude walks in with a LMG and starts lighting my team up. then he starts shooting at me. i took some serious damage, so i ran up and laid behind the couch for about less than 1 sec, got back up and killed the dude
