Vec: "The interesting job Spec is that they will be acting as Aircraft Commander.... a role normally reserved for the Observer. "
A fair comment if all QOIs were B1/A2 and there was no comms role for the plane. But back in the real world any pilot will need to be capable of taking the role of a/c cdr if the QOI is B2 (plenty of Obs do their first instructional tour on 750) and, of course, when the aircraft is used in the comms role.
