Halo Spartan Name Generator

Spartan names in Halo follow strict conventions that change with each generation of the program. Spartan-IIs, conscripted as children by Dr. Halsey, are known by their first name and a three-digit service tag: John-117, Kelly-087, Linda-058, Fred-104. The tag is a training number, not a rank, and canonically ranges from 001 to 150. Spartan-IIs almost never use surnames, because their identities were erased when they were taken from their families.

Spartan-IIIs, the expendable companies raised by Kurt-051, add a letter before the tag to mark their company: A for Alpha (Carter-A259, Jun-A266), B for Beta (Kat-B320, Lucy-B091) and G for Gamma (Ash-G099, Olivia-G291). Their given names are often orphan names or nicknames, and their tags climb into the low 300s. Spartan-IVs, recruited as adult volunteers, keep their full civilian names, so you get Sarah Palmer, Edward Buck, Jameson Locke and Holly Tanaka rather than tags.

To write a convincing Spartan, pick the generation first. A Spartan-II needs a short given name from any Earth culture plus a tag under 150; a Spartan-III needs a company letter and a tag; a Spartan-IV needs a believable modern first and last name. Then give the character a Fireteam or callsign, which is where nicknames like Noble Six and Sierra 117 come from.
