The objection to using a fleet tanker to shadow a Russian submarine

Would requiring Treasury staff to spend time aboard naval units prevent a fleet tanker being assigned to shadow a Russian missile corvette?

A tanker should not be assigned that role; the discussion cites a photograph of an RFA tanker escorting a Russian submarine as an example of the practice being criticized.

The question proposes making Treasury staff spend time aboard naval units and asks whether that would prevent a fleet tanker from being assigned to shadow a Russian missile corvette. The response rejects assigning a tanker to that task and recalls a photograph of a Royal Fleet Auxiliary tanker escorting a Russian submarine.
