For large sectors, the absence of a standardized method for identifying and sourcing regularly used parts can turn routine tasks like acquiring a screw or valve into a significant logistical challenge. This is especially true when operations span multiple organizations and countries, so to address such issues for military and defense purposes, the United States Department of Defense (DoD) developed the Federal Supply Classification (FSC) system in the mid-20th century. With this in mind, the FSC system also involves the use of Federal Supply Groups (FSGs) to cluster items under logical categories, which we will explore in this blog to highlight how they simplify and strengthen military logistics.
