T'Uerell
The following Borg rectangles were part of a Borg Collective which was controlled by the rogue Vulcan scientist, T'Uerell.

Aurelius spheres
Numerous rectangles participated in an assault on the Aurelius region. While the Borg cubes assimilated the planets in the region, the rectangles were among the other ships which preyed on the impulse transports which were carrying the evacuated civilians. The Borg ships were engaged by a Starfleet task force led by the USS Enterprise (NCC-1701-E), which allowed for fifteen transports, carrying the majority of the populations in the Aurelius region, to make it to Starbase 127, where the evacuees were safely transferred to warp-capable ships.
