The 4th Psychological Operations Group was activated in December 1967; it was created as a substantial expansion of capability, equipment, and staffing to address increased demands for PSYOP support by Allied units fighting the war throughout the Republic of Viet-Nam. The 6th PSYOP Battalion, deployed to Viet-Nam in 1965, became the new 4th PSYOP Group. The existing companies of the 6th Battalion were redesignated as Battalions under the 4th PSYOP Group as follows:
19th PSYOP Company: 10th PSYOP Battalion
244th PSYOP Company: 7th PSYOP Battalion
245th PSYOP Company: 8th PSYOP Battalion
246th PSYOP Company: 6th PSYOP Battalion
