[Halo] How many Spartan-IIIs are left?
gpt
IIRC there's at least 15 to 20 spartan 3s left in service by 2554. By the events of halo 4 all spartan 3s are officially retired or reassigned to the spartan 4 program. We never get hard numbers but at least a handful were still active as head hunter teams with unknown statuses and 2 teams of gamma company were still alive after the battle of onyx.
