Daredevil | Call of Duty Modern Warfare II Trophy

While affected by one Flashbang, kill two enemies in the Campaign or in Co-op

There are many ways you could achieve this trophy, but the mission that made it easy for me was during 'Kill or Capture.'

After crossing the field, the team will breach the first house where two enemy soldiers are by the entrance. Once Ghost opens the door, throw a flashbang and run towards it so you will be affected by it as well as you shoot around.
