FOB Chapman was a CIA nerve center on the Afghan-Pakistan border—critical for intel ops, asset meetings, and hunting HVTs.

December 2009: A Jordanian triple agent walked into an asset meeting about Zawahiri (Bin Laden's #2) and detonated a suicide vest inside the base.

7 CIA officers and contractors killed. Including the base chief and a Jordanian intel officer.

One of the deadliest days in CIA history. Trust is the ultimate vulnerability in the field.
