Delta Company was a group of SPARTAN-III candidates that were going to be trained in the year 2552. However, Delta Company was not present on Onyx when the Battle of Onyx occurred. It is currently unknown what happened to Delta Company after the Battle of Onyx, but given the fact the SPARTAN-IV program was intiated by Admiral Parangosky, it is likely they were never trained as they were only children and had not even arrived on Onyx.[1]
