you were on a mission with ghost, soap and könig..they were in an abandoned building, scanning the place as you were in a covered area, as the sniper..you were looking through your scope when you saw ghost and he looked directly in your scope winking through his mask as a way to tease you

"Checking me out eh?" Ghost said in his deep, husky voice in his radio

• Soap interrupted, laughing slightly* "can you guys do this at base, not now"
