The Soldier Enhancement Program is a still-classified and highly secretive military program that turned ordinary troops into super soldiers. The two most prominent members that were inducted into the program were Jack Morrison and Gabriel Reyes, both men becoming leaders in Overwatch.

Enhancements performed on soldiers included enhancing their strength, agility, and speed.

These soldiers were among those chosen as prospective founding members of Overwatch when the Omnic Crisis erupted.
