Fort Leavenworth, Kan. -- The Combined Arms Center's Combined Arms Doctrine Directorate participated in the Peruvian Army "1st International Symposium on Land Military Doctrine," in Lima, Peru, Aug. 16, 2019. This event marked the first-ever international doctrine development symposium with regional partners (Peru, Chile and Colombia) and serves to enhance multinational interoperability through the development of a common military language."The symposium marks the completion of phase one of Project Wiracocha, named after an Incan deity, believed to be the giver of life," said Carlos Soto, CADD employee and the U.S. Army's symbologist and terminologist. The goal of Project Wiracocha is to give new life to multinational interoperability in the region according to Soto."Much work lies ahead," Soto continued. "This is work that will establish a common military language -- language that supports national and multinational operations, in countering narco-trafficking and illegal mining, and assisting in disaster relief operations. The doctrine we're developing will help provide more effective military cooperation and regional stability."The symposium hosted over one thousand participants, including Peruvian Deputy Minister of Defense Jorge Moscoso; Commander of the Peruvian Army Gen. Jorge Celiz-Kuong; and attachés from the United States, Chile and Colombia. Gen. Celiz-Kuong reinforced the importance of establishing military doctrine that is interoperable with the United States, NATO and regional partners. He presented Soto with an emblem of Project Wiracocha as gratitude for the assistance provided by the Combined Arms Doctrine Directorate in this endeavor.During the conference, the Peruvian Army committed to use structured doctrine, providing a common military language in national/multinational operations. Common doctrine between the United States and partner nations enhances the ability to counter threats, share information and conduct operations while improving interoperability among the Peruvian Army, its regional partners and the United States Army.
