Cong (VC) members. Between 1968 and 1972, the Phoenix Program captured 81,740 VC members, of whom 26,369 were killed. The program was also successful in destroying their infrastructure. By 1970, communist plans repeatedly emphasized attacking the government's "pacification" program and specifically targeted Phoenix agents. The VC also imposed quotas. In 1970, for example, communist officials near Da Nang in northern South Vietnam instructed their agents to "kill 400 persons" deemed to be government "tyrant[s]" and to "annihilate" anyone involved with the "pacification" program. Several North Vietnamese officials have made statements about the effectiveness of Phoenix. MAC-V SOG (Studies and Observations Group, which was originally named the Special Operations Group, but was changed for cover purposes) was created and active during the Vietnam War. While the CIA was just one part of MAC-V SOG, it did have operational control of some of the programs. Many of the military members of MAC-V SOG joined the CIA after their military service. The legacy of MAC-V SOG continues within SAC's Special Operations Group. On May 22, 2016, the CIA honored three paramilitary officers with stars on the memorial wall 56 years after their deaths. They were David W. Bevan, Darrell A. Eubanks, and John S. Lewis, all young men, killed on a mission to resupply anti-Communist forces in Laos. They were all recruited from the famous smokejumpers from Montana. One former smokejumper and paramilitary officer, Mike Oehlerich, believed he should have been on that flight, but they accidentally missed their pickup to the airport. They got stuck in Bangkok and so another crew – Bevan, Eubanks, and Lewis – flew that mission on August 13, 1961. "We had no idea anything happened until we got back the next day, and that's when they told us that they went into a canyon and tried to turn around and got into bad air," he said. CIA officials told him days after the crash that Lewis had jumped out of the plane, rather than remain inside. "When they told me that, I teared up," Oehlerich recalled. "It was something John and I had talked about – 'Don't go down with the airplane, your chances are better if you get out.'"
