Two sectors - one at the front and one at the rear, would be referred to as what?
Sectors should be allocated according to their location, rather than the order in which they are established.
Where two sectors are established, one at the front and one at the rear of a building then these will be Sector One and Sector Three.

Where a Sector Commander has been appointed, for example to the rear of a building, is there a requirement to assign a Sector Commander to the front?
No
It is important to note that where a Sector Commander has been appointed, for example to the rear of a building this does not necessarily mean that a separate Sector Commander has to be allocated to the front of the building if the Incident Commander is satisfied that they can retain a satisfactory level of command.
