The division oversees and synchronizes activity of 18 courier stations worldwide to service over six thousand accounts.

The DCS was formerly the Armed Forces Courier Service (ARFCOS) but was reorganized and renamed in 1985 after the Walker spy case.

The ARFCOS charter was updated seven times over the next 30 years to reflect changes in the armed forces, military doctrine, and operational procedures.

Key to this are the following major affiliations: The Gulf War provided the first real-world contingency deployment test of the DCS.

Eight days after Iraqi tanks entered Kuwait, a seven-man DCS station was deployed to HQ, Central Command in Riyadh, Saudi Arabia.

By the end of the Gulf War, DCS couriers had provided over one million pounds of command, control, and intelligence material.
