Final answer:
PERSCO teams must update DCAPES at least every 24 hours during exercises, deployments, and contingency operations as per Air Force Instruction.
Step-by-step explanation:
The Deliberate Crisis Action Planning and Execution Segments (DCAPES) are an essential component of the United States Air Force's (USAF) operational planning and execution. Personnel Support for Contingency Operations (PERSCO) teams are responsible for personnel accountability and reporting in such environments. According to the Air Force Instruction (AFI), PERSCO teams are required to update DCAPES no less frequently than every 24 hours during exercises, deployments, and contingency operations to ensure accuracy of personnel status and availability.
