Replying...
Intro. Adler later joined the Special Activities Division in 1966 and was assigned to the MACV-SOG in 1967 to investigate Soviet activity in Vietnam. On 26 January 1968, during Operation Fracture Jaw, Adler found minor intel that hinted towards the existence of legendary KGB agent Perseus. Shortly afterwards, he defended Firebase Ripcord alongside Lawrence Sims and other MACV-SOG operatives until they were able to extract the nuclear device from the base. Bell's supposedly false memories in "Break on Through" are Adler's memories of his combat in Vietnam. After Vietnam, Adler disappeared from and only sporadically appears in the CIA's records but continued to be affiliated with a number of clandestine operations. His deep knowledge of covert tactics, fluency in Russian and German, and mastery of espionage make him one of the few key operatives that the CIA can consistently rely upon.
