AETC Studies and Analysis The Air Education and Training Command ( AETC ) Studies and Analysis Squadron ( SAS ) has roots that date back to World War II , as a connection can be traced to the Air Corps Flying Training Command of that time period . The AETC is responsible for developing trained and motivated personnel for the United States Air Force , whilst the SAS oversees the administrative component of the military body , using evaluation tools to " predict resource requirements for more than five years into the future " . History . The original Ravens served in World War II as the 21st Bombardment Group with a heavy bombardment mission . During the Vietnam War , they provided visual reconnaissance , airborne forward air control for tactical offensive operations and gave theater indoctrination flight checks for newly assigned aircrew members as the 21st Tactical Air Support Squadron . In May 1991 , the 3307th Test and Evaluation Squadron was established to perform tests and evaluations of new Air Training Command ( ATC ) systems such as aircraft , simulators and software to determine if these acquisitions met operational requirements . Seventeen months later , in September 1992 , the 3307 TES inherited the history and honors of the Ravens by assuming the designation of the 21 TES . In March 1994 , the 21 TES was re - designated the AETC Studies and Analysis Flight and assigned directly to HQ AETC . In April 1997 , the AETC Studies and Analysis Flight and the 602nd Training Support Squadron ( 602TRSS ) , Edwards AFB , CA , were combined and re - designated the AETC SAS . The 602 TRSS was re - designated Detachment 1 SAS and brought with it extensive training development experience in nearly every major weapon system acquisition since 1972 . In November 1997 , the squadron established the Technology Innovation Flight ( IT ) to determine the effectiveness and return on investment of new concepts and off - the - shelf technology in education and training . In January 2003 , AETC inactivated the three Operating Locations operating under Detachment 1 SAS . In May 2003 , Detachment 1 downsized from 13 authorizations to 5 and deleted the training assessment function . In October 2003 , Detachment 1 was re - designated as Operating Location A ( OL - A ) . OL - A was inactivated per Special Order G - 08 - 11 effective 31 July 2008 . The personnel at OL - A were relocated to AETC SAS , Training Analysis ( TA ) Flight . In June 2010 , Strategy Management joined SAS in order to be responsible for the command headquarters lead program managers for AETC Strategy Management . Later , in November 2011 , Strategy Management changed to the Strategy Analysis Flight to be responsible for the Directorate of Plans , Programs , Requirements and Assessments Strategy Management .
