You heard previous testimony by a witness talking about the Canadian Forces' tracking of personnel on release. That process is centralized through the central registries.
Obviously, if someone's a member of that unit or under the care of that unit at the time, the unit is aware of it. It's not a responsibility of the JPSU to track those. The specifics of those would have to come from elsewhere in the department, but we track the care and feeding of people for whom we're responsible at the time.
