Following a series of reactivations and redefinitions, it participated in 14 campaigns in Vietnam from 1966 to 1972 as the 593d General Support Group assigned as HQ Qui Nhon Sub Area Command of the 1st Logistics Command, earning its second Meritorious Unit Commendation and the Vietnamese Cross of Gallantry with Palm.

The Group was immediately responsible for many post-support missions critical to the day-to-day operations of Fort Lewis, while simultaneously being prepared to deploy worldwide in support of I Corps, PACOM, Homeland Defense and War on Terrorism requirements across the full spectrum of Army, Joint and Interagency operations.

Brigade personnel and units have supported a variety of missions ranging from SBCT National Training Center rotations, conducting the command, control and onward movement of all equipment during the redeployment of the 4th Brigade Combat Team, 2d Infantry Division, to the Japanese CALFEX while annually hosting the Washington Special Olympics.

Between November 1998 and February 1999, the 593d Corps Support Group successfully joined with other military personnel to restore hope in that part of Central America.

*[1] 593d SB became the first command of the CENTCOM Materiel Recovery Element (CMRE) mission in Afghanistan in June 2012.
