This reproduction is based on a GWOT-era Aco, 1st PSYOP Battalion design identified in the artwork as Military Information Support Team Detachment 1A40. The Spanish-language “Persuade · Cambia · Influencia” treatment and El Gallo Negro motif fit the battalion's long regional association with U.S. Southern Command and Latin America. The design itself dates the detachment artwork to 2016.
1st PSYOP Battalion has a long special-operations history and, after the 8th Psychological Operations Group was activated in 2011, became one of its regional battalions. Public ARSOF histories document 1st POB teams working across Latin America during the GWOT era, including Colombia and Central America. Public sources do not identify Detachment 1A40's specific operating location, so this reproduction preserves the unit artwork without assigning it to an unsupported country or mission.
Available on Next Level cotton T-shirts in Heather Gray, Olive Drab, and Sand, or the Soffee 670-1 compliant military T-shirt in Coyote Brown / Tan 499.
Also available as: Champion Powerblend hoodie.
