4th Psychological Operations Group
The 4th Psychological Operations Group (Airborne) (or 4th POG)(A) is one of the United States Army's active military information support operations units along with the 8th Psychological Operations Group (Airborne), which was activated 26 August 2011 at Fort Liberty. The 8th Group has responsibility for the 3rd and 9th Psychological Operations battalions while  the 4th Group has responsibility for the 1st, 5th, 6th, 7th, and 8th battalions. On 21 June 2010, an announcement was made that the military intends to rename psychological operations, or PSYOP, to Military Information Support Operations. The decision, made a few days earlier by Admiral Eric Olson, Commander, United States Special Operations Command and Army's Chief of Staff General George Casey, was propagated through a memo dated 23 June 2010. By October 2017, the U.S. Army Special Operations Command (USASOC) reverted its decision changing their name back to PSYOP stating, "Psychological operations refers to the name of units, while MISO refers to the function that soldiers in PSYOP units perform".The unit is based at Fort Liberty, North Carolina and is a part of the 1st Special Forces Command (Airborne), under the United States Army Special Operations Command.
