 The program established that participants could receive a Reserve commission as a second lieutenant by completing four successive summer courses (titled Basic, White, Red, and Blue), but only 5,000 such commissions were awarded over the 20-year history of the CMTC.Apparently, no records exist that document total participation, but it is estimated that 400,000 men had at least one summer of training.Among known participants were Harry S. Truman, Ronald Reagan, Robert Penn Warren, Walter S. McIlhenny, Chuck Yeager, John J. McCloy and William Guarnere.
