All PCS, Low Cost PCS and Reservists ordered to active duty (unless reporting to the MOB Processing Center) processing will be accomplished at this location. PCA within MCB Quantico will be handled by the Outbound Branch.
All Marine Corps personnel reporting to Quantico during normal working hours will report in FIRST to their respective S-1 admin office, then follow up with the Installation Personnel Administration Center (IPAC) located on the second deck of Building 2006, Hawkins Avenue, (Headquarters & Service Battalion Building).
