|Deep and Hard|
|Description||Complete the game on Hardened or Veteran difficulty.|
Deep and Hard is a campaign-related achievement in Call of Duty 4: Modern Warfare. It requires the player to complete the singleplayer on Hardened or Veteran difficulty. Completing "Mile High Club" is not required for this achievement.
- The title of this trophy is a reference to the opening scene of Mile High Club when one of the 141 operatives says, "We're going deep, and we're going hard."
