Base Segundo Terra
From Halopedia, the Halo wiki
Base Segundo Terra is a UNSC military base located near Mexico City on the North American continent of Earth. During the Battle of Earth, the Spartan Blue Team used the base as a staging point to attack the Covenant incursions in Havana and the Yucatan Peninsula.
"Segundo Terra" roughly translates from Spanish, with some grammatical caveats, as "second earth" in English.
