The following announcement was written by Fold3:

The Defense POW/MIA Accounting Agency (DPAA) is an agency within the United States Department of Defense. Their mission is to recover the remains of military personnel who are listed as prisoners of war or missing in action from past conflicts. We’ve added a new collection of indexed records for the estimated 82,000 American military and civilian personnel still missing in action. The index covers multiple conflicts including WWII, the Korean War, the Vietnam War, the Cold War, and more recent conflicts including Operation Desert Storm and Operation Iraqi Freedom. 

The DPAA collection is divided into two groups. Group A, which consists of 38,000 missing service members whose remains are considered recoverable; and Group B consists of 44,000 missing service members whose remains are considered unrecoverable.z
