I normally use the guided missile or Counter UAV with the Harrier and either the Pavelow or Chopper Gunner, but I decided to mix it up one match and selected Harrier, Emergency Airdrop, and Pavelow. The kills needed for these three are 6, 7, and 8. When I got all three in a row, I got a new title. I say challenges because I think it’s a challenge to complete the tasks in order to get all the titles and emblems. And they’re hidden because there’s no instructions on how to unlock all the titles and emblems!
