Baseplate

"BASEPLATE" is the codename for the British Special Air Service Command Central hailing from the Call of Duty Universe.

"BASEPLATE" is simular to the United States' "OVERLORD", both serving as the Headquarters for its military operations, giving orders to soldiers in the field.

Like "OVERLORD", "BASEPLATE" may not be just one individual.

As of Modern Warfare 3, the primary commander of "BASEPLATE" is Captain Price's mentor MacMillan.
