"Rawlings" was a clone captain during the Clone Wars, being a member of Raven Squadron in his years with the Republic. Born on Kamino in 31 BBY, he was the sole survivor of an engagement with his previous squad, after which he was moved into Raven Squadron as told.
The captain participated in many battles until Raven Squadron's last battle on Raxus Prime, where a rumored droid factory turned out to be a Separatist base. Rawlings was killed in the major battle that ensued, which resulted in the death of half of Raven Squadron.
