FRBC storage and DRBC processing are organic to select naval vessels (Table 2), some garrison medical treatment facilities (MTFs), and Service blood depots in the European Command, Africa Command, and Indo-Pacific Command areas of responsibility. Deployed MTFs and Medical Detachment Blood Support units do not have the organic mission or capability to store and process frozen RBCs. Use of this capability is based on operational necessity. Upon completion of the deglycerolization process, the produced DRBCs are typically provided to Role 2 and higher MTFs due to the 14-day shelf life.
