John Stryker "Tilt" Meyer (born 1946) is an American author and U.S. Army Special Forces combat veteran of service in covert reconnaissance with the Studies and Observations Group, also known as MACV-SOG.

[3] As U.S. involvement in the Vietnam War escalated, the United States began deploying Special Forces "A-teams" (Operational Detachment Alpha, or ODA, teams) to Southeast Asia in support of counterinsurgency operations against the Viet Cong, North Vietnamese and other Communist forces.

A Green Beret, Meyer joined MACVSOG, signing a 20-year secrecy agreement, and served two tours of duty in 1968 and 1969 running missions in Vietnam and "across the fence" in Laos and Cambodia.

He arrived at FOB 1 Phu Bai in May 1968, where he joined Spike Team Idaho, which transferred to Command & Control North (CCN) in Da Nang January 1969.

In addition to his continued work as an author, speaker, and veterans advocate, Meyer also hosts SOGCast, a podcast featuring untold stories of MACVSOG and those of fellow Green Berets and Special Forces operators.
