High and Mighty Achievement
High and Mighty10
Wipe out the Elite Russian Sniper Team from the rooftopsNear the end of Mission 8, 'Kreuzberg HQ', you will reach a building where you find some documents. There will be a quick cutscene where you are getting sniped. On the rooftops of the buildings surrounding the square will be 8 snipers. You need to kill each one of them before exfiltrating and ending the mission.
To help you identify where they are, wait for the glint of their scope and tag them with your binoculars. If playing on 'Cadet' you might get injured but not enough for it to be fatal. Take out all 8 snipers and the achievement is yours.
