The lineage of 1109^th Theater Aviation Sustainment Maintenance Group (1109^th TASMG) traces back to May 1775, originally organized in Norwich, Conn., as the Norwich Light Infantry, that was part of the 20^th Regiment of the Connecticut Militia. Over the centuries, it underwent numerous redesignations and transformations, serving in major conflicts including the Revolutionary War, Civil War, World War II and the Global War on Terrorism. The unit has earned several prestigious decorations, including the Presidential Unit Citation, the Meritorious Unit Commendation and the Philippine Presidential Unit Citation for its service.

In modern times, the unit’s heritage continues through its evolution from artillery and transportation roots into a critical aviation sustainment unit. In fiscal year 2012, Company B, 1109^th TASMG, joined the 103^rd Troop Command of the Hawai‘i Army National Guard at the Waiawa Armory in Pearl City, Hawaii. From its inception, Co B 1109^th TASMG has served as a critical sustainment element within the larger aviation support framework.

In 2019 and 2020, Co B 1109^th TASMG took part in annual training alongside a WARTRACE unit in Groton, Conn. During the COVID-19 pandemic, Soldiers provided logistical support to Task Force QRF and Task Force Maui. Co B 1109^th TASMG played a key role in operations on Maui, where they performed critical vehicle repairs and maintenance to support pandemic response logistics.

Co B 1109^th TASMG remained engaged in community support as well. In 2021, Company B soldiers participated in a statewide blood drive in Honolulu to help address local shortages. In 2022 the unit demonstrated excellence in field food service by competing in the prestigious Philip A. Connelly competition. Their performance showcased top-tier execution of military culinary operations, including proper setup, food preparation and sanitation.

In 2023 and 2024, the Maintenance and Medical sections supported major training events at the Joint Readiness Training Center in Fort Johnson, La. In June 2024, the Distribution Section conducted a 40-hour Combat Lifesaver course at Waiawa Armory, certifying 20 soldiers from across the 103^rd Troop Command. That same month, the Maintenance Section completed its annual maintenance requirements, ensuring operational readiness and equipment functionality.

Co B 1109^th TASMG, remains a mission-critical component of Hawai‘i’s aviation sustainment capability. Through its diverse logistical, medical, and maintenance functions, the unit continues to support both state and national objectives with professionalism, adaptability and excellence.
