We only ever hear Bashiir Salahuddin referenced by his first name.

Bashiir is CAF (Canadian Armed Forces) and supports Cpl. Rory Williams when he intervenes in Garik Shayk's repair of Halo Sunchaser's electrified sword.

We meet Bashiir Salahuddin in Book 10 of The Human-Hybrid Project, The Russian's Revenge.
