History edit
Reserve units have served in Puerto Rico since 1922 when the 373rd Infantry was moved to the Organized Reserve and headquartered in San Juan, Puerto Rico.
In 1973, the Support Group was placed directly under First United States Army. By 1974, the 166th Support Group was given full mission control of all United States Army Reserve units in Puerto Rico and the United States Virgin Islands and assumed the mission and functions of a major U.S. Army Reserve Command, under First U.S. Army.
The Garita patch is worn by members assigned to this unit.[2]
