Air force assigned mission-air force assigned mission (afam) any cap activity authorized by the air force to use an a or b mission symbol. Amissions are generally considered air force reimbursable missions that are funded and provide federal insurance coverage. Bmissions are generally considered air force non-reimbursable missions that are normally funded by a federal, state, or local agency, the cap wing, or individual members and provide federal insurance coverage. Bmissions must have some level of federal interest in order for the mission to be authorized to receive federal insurance coverage.
