The III MEF Information Group (III MIG) can trace its lineage back to 1 October 1988 with the formation of the 3d Surveillance Reconnaissance Intelligence Group (3d SRIG). Initially, the SRIG consisted of an Intelligence Company and a Headquarters Platoon. Its mission involved sending detachments to Marine Air Ground Task Force units of the III Marine Expeditionary Force (III MEF) deployed to areas ranging from the Indian Ocean to Northern Japan and Korea. On 1 October 1990, 3d SRIG was officially activated, consisting of Headquarters and Service Company, 7th Communication Battalion, Intelligence Company, and Detachment Force Reconnaissance Company. On 6 January 1990, the subordinate elements of 3d SRIG were relocated from various camps throughout Okinawa to a single location at Camp Hansen. The 7th Communication Battalion was established as a separate Battalion under the Commanding General, III MEF on 7 June 1994.

In response to Headquarters Marine Corps efforts to streamline command and control, 3d SRIG was deactivated and Headquarters and Service Battalion (HQSVCBN), III MEF was established on 31 May 1995. The battalion gained its structure by integrating the elements of the SRIG with the Headquarters and Service Company. This restructuring coupled a headquarters with commodity services to better support the III MEF Command Element.

Headquarters and Service Battalion, III MEF provided training, and administrative and logistical support for almost 1,000 Marines assigned to Headquarters and Service Company, 5th Force Reconnaissance Company, Intelligence Battalion, and the III MEF Special Operations Training Group. Headquarters and Service Battalion also performed the Headquarters Commandant function for the III MEF Command Element, and deployed its engineers, motor transport, medical, supply, logistics, and administrative personnel and equipment to U.S. Pacific Command directed operations and exercises throughout the Asia-Pacific region.

On 1 October 1999, HQSVCBN, III MEF was deactivated and the III Marine Expeditionary Force Headquarters Group was activated. Now consisting of more than 1,700 Marines and Sailors, the Group includes 7th Communication Battalion, 3d Intelligence Battalion, 5th Air Naval Gunfire Liaison Company (-), 3d Radio Battalion, 3d Special Operations and Training Group, and the Headquarters and Service Company, which includes the III MEF Command Element and the III MEF Band. III MHG exercises administrative control over its subordinate commands. It continues to provide training, administrative and logistical support while in garrison, and maintains a deployment-ready posture in preparation for supporting III MEF during any type of contingency.

On 8 September 2017, III Marine Expeditionary Force Headquarters Group was re-designated in a ceremony as III MEF Information Group, highlighting the beginning of a new era of modern Marine Corps information warfare. The MIG’s primary mission is to defend important information technology capabilities from adversaries, which will allow the MAGTF to exploit technological warfare opportunities via a network force.

Sexual Assault is a criminal act and will not be tolerated. The Marine Corps' goal is to eliminate sexual assault within the Corps and to assist those Marines and sailors assigned to Marine Corps units affected by sexual assault. The 3D MLG Sexual Assault Prevention and Response Program provides 24/7 support and advocacy to all active duty Marines and sailors who are victims of sexual assault. The Sexual Assault Prevention and Response Program addresses the prevention of sexual assault through awareness, education and training. We also ensure that all Marines who are victims of sexual assault are "treated with dignity, sensitivity, and without prejudice." Seeking Support The first priority of the Sexual Assault Prevention and Response Program is the care of Marines. Many victims of sexual assault do not report the crime to anyone. In order to ensure that victims get the medical treatment and support services that they need, Marines have two reporting options for sexual assault. Restricted and Unrestricted Reporting Restricted Reporting If a Marine wants to receive medical treatment and support services without triggering the official investigation process, he or she can make a confidential report to any of the following individuals: Sexual Assault Response Coordinator (SARC) Uniformed Victim Advocate (UVA) Victim Advocate Healthcare Provider or other medical personnel Chaplain

Expand List item 12417Collapse List item 12417  Definitions

The term "sexual assault" is defined as intentional sexual contact, characterized by use of force, threats, intimidation, abuse of authority, or when the victim does not or cannot consent. Sexual assault includes rape, forcible sodomy (oral or anal sex), and other unwanted sexual contact that is aggravated, abusive, or wrongful (to include unwanted and inappropriate sexual contact), or attempts to commit these acts. "Consent" means words or overt actions indicating a freely given agreement to the sexual conduct at issue by a competent person. An expression of lack of consent through words or conduct means there is no consent. Lack of verbal or physical resistance or submission resulting from the accused's use of force, threat of force, or placing another person in fear does not constitute consent. A current or previous dating relationship by itself or the manner of dress of the person involved with the accused in the sexual conduct at issue shall not constitute consent.
