PES F is a category under the PES (Physical Employment Status) grading system to determine the suitability of deploying military personnel for combat and in other vocations.

Once an individual in military service has undergone a PES assessment, he receives a score which enables him to be categorised from PES A to PES F.

PES F is the lowest category which denotes that he is medically unfit for any form of service.
