About this Unit
The 102d Army Reserve Command (ARCOM) DCSIM (Deputy Chief of Staff for Information Management) was a key staff element responsible for overseeing information systems, communications, and automation support within the 102d ARCOM. Based historically in the midwestern United States, the 102d ARCOM provided command and control of Army Reserve units across several states, including Missouri and Illinois, throughout the late 20th century. The DCSIM section enabled operational readiness by ensuring robust and secure communications, supporting training, mobilizations, and administrative functions. During its tenure, the 102d ARCOM DCSIM adapted to evolving technologies and played a critical role in modernizing information management before Army Reserve command structures were reorganized in the 1990s and early 2000s.
