In 2009, the Air Force Culture and Language Center (AFCLC) developed the General Officer Pre-Deployment Acculturation Course (GOPAC), which has been delivered to dozens of Air Force GOs enroute to overseas locations across all the commands. AFCLC has expanded the program to include GOs headed to both deployment and permanent assignments (Pre-Deployment/Pre-Assignment Acculturation Course – PAC). AFCLC also delivers instruction to Colonels headed to group command and senior staff positions (known as Commanders PAC or COMPAC) and to Chief Master Sergeants headed to Command Chief positions (known as CHIEFPAC). PACs provide formal, tailored instruction on culture/region with some focus on language/communication skills.
