Similarly, you may ask, what is an AEF indicator?The AEF Indicator is a letter and number combination assigned to military members aligning them with an AEF cycle, which is used to identify when Airmen deploy. The AEF Indicator identifies the person who is eligible for that deployment cycle. “AEF Indicators are assigned [based on] unit requirements,” Cooper said.Also Know, how often do airmen get deployed? Every 20 months, your Airman may go on deployment. Your child should plan to be deployed out of country at least once in their Air Force career. The length of an Air Force deployment ranges from four to 12 months depending on an Airman’s specific job, location and mission requirements. Also question is, how are you assigned to your specific AEF band? Airmen are assigned to one of five tempo bands based on their career fields. Each band is then broken into blocks that represent deployment and dwelling (or preparation) periods. Airmen’s unit type codes, or career fields, dictate the band they are assigned to, or, more specifically, the frequency of their deployments.What is an AEF vulnerability window?The AEF vulnerability period is the period of time the forces aligned in a specific AEF block are susceptible to initial deployment and will mirror the vulnerability period (AEF block) to which their unit’s UTCs are aligned. Only one AEF block from each Tempo Band will be vulnerable at a time.
