206th Regional Support Group

206th Regional Support Group is a United States Army Reserve unit which controls two Engineer Battalions (the 458th EN BN and 844th EN BN) and seven rank-heavy, 15 soldier Engineer Facilities Detachments (305th EFD, 443rd EFD, 673rd EFD, 904th EFD, 729th EFD, 763rd EFD, and the 415th EFD) each led by a Lieutenant Colonel. These are located in New York City, New York, Johnstown, Pennsylvania, Ft. Meade, Maryland, Annville, Pennsylvania, Decatur, Georgia, Ft. Jackson, South Carolina, and Knoxville, Tennessee, respectively. Of the two Engineer Battalions, one (the 458th EN BN) is headquartered in Johnstown, Pennsylvania, and the other (the 844th EN BN) is headquartered in Knoxville, Tennessee. Originally under the 103rd ESC since its creation in 2006, the 206th RSG switched commands to the 412th TEC on 1 October 2019, and was relocated by the US Army Reserve Command from its original location in Springfield, IL to a new location in McLeansville, North Carolina, set to go into effect in January 2021, shortly after the unit returned from Afghanistan in July 2020. The unit relocated its equipment in September 2020, and officially transported the guidon to its new home for its first Battle Assembly at the Mcleansville Army Reserve Center in March 2021. The first two Battle Assemblies of Calendar Year 2021 were conducted telephonically due to the COVID-19 pandemic, so March 2021 was the first Battle Assembly the 206th RSG HHC held at its new location.
