3d Radio Battalion Lineage:

3rd Radio Battalion, located aboard Marine Corps Base Hawaii in Kāneʻohe Bay, traces its lineage to 1943 with the creation of the 3d Radio Intelligence Platoon. Most recently, since August 2003, the Battalion has served in a dual support role of both I and III Marine Expeditionary Force. Following the units return from Iraq in February 2006, 3d Radio Battalion began focusing on supporting the Global War on Terrorism. In October 2008 3rd Radio Battalion deployed as part of SPMAGTF-A to Helmand Province in Southern Afghanistan as part of the ISAF troop surge, and participated in several major operations including the Battle of Now Zad as well as Operation Khanjar.

The history of the Radio Battalion:

In June 1943, 2nd Radio Intelligence Platoon was activated at Camp Elliott, California. The unit took part in the Battle of Guadalcanal and the Battle of Peleliu. The 3rd Radio Intelligence Platoon was also formed in June 1943 and took part in the Battles of the Kwajalein Atoll and Okinawa. From World War II until the early 1960s, various units performed radio intercepts, growing from platoon to company and, in 1964, to 1st Radio Battalion. Sub-units of the battalion were deployed to Vietnam from 1967 to 1975, including participation in evacuation efforts during the Fall of Saigon. In the early 1980s, 2nd Radio Battalion was part of the multinational peacekeeping force in Beirut, Lebanon. More recently, Radio Battalions served in Operation Desert Storm, Somalia, Kosovo, the 2003 Invasion of Iraq, and the 2004 Operation Phantom Fury in Fallujah. Radio Battalions also send detachments to augment intelligence efforts at Guantanamo Bay Naval Base, Cuba, and at other bases throughout the world.

In Afghanistan Radio Battalion has proven especially effective against improvised explosive devices.
