Doctor, Doctor

Doctor, Doctor is an Achievement in Halo: Reach. It is unlocked when a player uses a Health Pack to heal themselves after taking damage.

Trivia

 * This achievement is very similar to the achievement "Heal Up" in Halo 3: ODST, which also requires the player to use a Health Pack. The symbol of both achievements uses a medical symbol.
 * Players will at some point in campaign get wounded, specifically, the player will have low health in the campaign level Exodus, so unless the player doesn't care about his/her health, the player will acquire a health pack.
