Pōhakuloa Training Area (PTA) was first used during World War II as a Marine Corps artillery live-fire training area. U.S. Marines from the 2nd Marine Division and the 5th Marine Division trained at PTA and on the western side of the Big Island in preparation for the Iwo Jima and Saipan campaigns.

During World War II, few permanent structures existed; when the Marines trained at PTA, they slept in tents. After the war, PTA fell under the control of the Hawaii Territorial Guard, and in the mid-1950s, the Army took over PTA. From 1955-58, Soldiers from the 65th Engineer Company built the distinctive Quonset huts, which are still in use.

PTA's 133,000 acres include an 80-acre cantonment area with a fuel yard, fire and police departments and an airfield with a 3,700-foot runway. The cantonment area also provides units with task-force headquarters, dining facilities, a troop medical clinic, a theater and the only Quonset-hut chapel in the Army.

The installation can support up to 2,300 military personnel with rations, ice, fuel and transportation.

PTA's firing ranges allow units to conduct small-arms and crew-served weapons familiarization training and qualifications, as well as artillery and mortar live fire. Through the years, PTA’s ranges and training areas have helped Army, Marine, Air Force and Navy units maintain their combat readiness and prepare for war. Most recently, 25th Infantry Division units, Kaneohe-based Marines and Hawaii Army National Guard Soldiers prepared at PTA for combat operations in Iraq and Afghanistan.

In addition to being a prime training area for military forces in the Pacific region, PTA is a vanguard of environmental and cultural protection. PTA Natural and Cultural Resources staff include more than 50 professionals dedicated to preserving and protecting endangered and threatened plants and safeguarding cultural resources at PTA.

Today, PTA stands as the premier military training area in the Pacific region. Units from all U.S. military services, as well as allied militaries, train at PTA, because it offers realistic training opportunities not found elsewhere. With several new construction projects underway, PTA stands ready to support military training well into the future.

The PTA command team and staff embody the IMCOM motto: “Sustain, Support, and Defend.”


Pōhakuloa Training Area provides a quality joint/combined arms facility that provides logistics, public works, airfield support, and environmental and cultural stewardship in support of the USARPAC training strategy while maintaining an enduring partnership with the local Hawaiian community. 


  • Provide and maintain an austere but safe training facility that supports realistic training.
  • Setting the standard for environmental compliance as well as natural and cultural resource stewardship.
  • As an active member of the community, develop productive relationships with state, county, and civic organizations

Aloha … Welcome to U.S. Army Garrison-PTA, Big Island, Hawaii

U.S. Army Garrison-Pōhakuloa Training Area (PTA) is part of the U.S. Army Installation Management Command-Pacific Region. Our mission is to provide a quality joint/combined arm facility that offers logistical and training support as the centerpiece of the U.S. Army-Pacific (USARPAC) collective training strategy for Hawaii, while maintaining and enduring partnership with the local community.

PTA is located on the Island of Hawaii, 250 air miles from Oahu and at 6,200 feet elevation in the saddle between Mauna Loa, Mauna Kea and the Hualalai Volcanic mountains. We are the largest Department of Defense installation in Hawaii consisting of more than 133 thousand acres.

The "Big Island" of Hawaii is the largest island in the Hawaiian island chain and is well known for its active volcanoes, black sand beaches and Kona coffee. It is less well known as home for more than sixty years to a major U.S. military facility that serves as the primary training and largest maneuver area in the Pacific for joint, interagency and multinational forces.

Our cost of living is one of the highest in the nation. PTA is considered a remote assignment, having very limited military resources; we have no on-post family housing, commissary, or medical facilities - uniformed service members and civilian employees alike have to utilize the local economy.

Most of our civilian and military families live in Hilo, on the windward (eastern) coast, located approximately 35 miles from PTA. Hilo is the largest city on the island and the headquarters for the county government. The remaining families live in the north or west part of the island in Waimea or Waikoloa area, approximately 40–50 miles from PTA.

There are two newspapers serving the Island of Hawaii: the Hawaii Tribune Herald and West Hawaii Today. Television news stations operating in Hawaii include KHON, KGMB and KITV.

All newcomers, both uniformed service members and civilians, will be assigned a sponsor to assist you and your family; the deputy commander and command sergeant major assign sponsors.

To request for welcome packet, contact USAG-PTA’s administrative office at 808-969-2400/2401/2402.

The Island of Hawaii is an exciting place to live and work. The terrain ranges from rocky seacoast and beaches, to mountain rain forests, to pasture and high desert; all a product of ongoing volcanic activity. In addition to the wide variety of natural beauty, the island has a unique Hawaiian culture. Many say the spirit of Hawaii thirty years ago remains unspoiled by the affect of tourism.

Hawaii residents have a long history and can teach you a great deal about Hawaiian culture and customs. The people of Hawaii are warm and friendly. Prepare yourself to truly get to know Hawaii and the aloha spirit.

Pōhakuloa Training Area (PTA) is located between Mauna Loa, Mauna Kea and the Hualalai Volcanic Mountains. PTA can be reached from Oahu either by direct military helicopter or military fixed wing flights to PTA's Bradshaw Army Airfield or by commercial airlines to either Hilo or Kona.
