 United States: The U.S. Army 25th Infantry Division is the primary jungle warfare unit in its size. The 25th Infantry Division conducts military operations primarily in the Asia-Pacific region; it also operates the Jungle Operations Training Course, Jungle Environment Working Group, and the Lightning Academy Jungle School.

Jungle warfare training: 

India: The Counter-Insurgency and Jungle Warfare School (CIJWS) located in Vairengte, Mizoram, India, is the primary jungle warfare training center for Indian forces.

Brazil: The Jungle Warfare Training Center (CIGS) in Brazil is the primary jungle warfare training center for Brazilian forces. They seek to copy the capacities of units of homologous commands.

United States: The Jungle Operations Training Center (JOTC) located at Schofield Barracks in Oahu, Hawaii is the primary jungle warfare training center for American forces. Opened in its present rendition in 2013, JOTC is operated by the 25th Infantry Division and primarily trains personnel of the 25th Infantry Division, special forces, and foreign partners. Hawaii was chosen as the location for JOTC due to its climate, geography, capacity, and operational history in jungle training within the Pacific.

 
Jungle warfare training is not new to this organization in Hawaii or the United States. During World War II the JOTC, also known as the Pacific Combat Training Center, was established in Hawaii to teach soldiers survival and fighting skills in tropical environments. Over 300,000 U.S. military personnel were trained in jungle fighting prior to deploying throughout the Pacific. Between 1956 and 1965, this same installation in Hawaii was home to the Jungle and Guerilla Warfare Training Center followed by the Recondo School from 1971 to 1979. The U.S. Asia-Pacific Rebalance Strategy necessitated jungle warfare training for the U.S. military be increased in priority. JOTC's revival at its original location in Hawaii is in part due to closure of the Fort Sherman, Panama JOTC location in 1999. 
Another jungle warfare training center, Camp Gonsalves, is operated by the United States Marine Corps on northern Okinawa Island, Japan.
