As of approximately 19 July 2011, the US Army has Senior Contracting Official Authority for PACOM (for Joint Operations). Col Michael Hoskin at the 413th Contracting Support Brigade (Fort Shafter, Hawaii) performs this role. Previously it was PACAF/A7K.
The Senior Contracting Official for the Air Force is Col Thomas Robinson, PACAF/A7K (Joint Base Pearl Harbor-Hickam, Hawaii).
13 AF/A7K is the responsible Air Force Contracting entity to respond to any event or crisis in PACOM area of operation (AOR) that does not have a contracting activity located there, whether war-time or Humanitarian Assistance/Disaster Relief (HA/DR). For example Indonesia, etc. This is one of my roles.
