Sabaody Marine Base

The Sabaody Marine Base is a Marine Base located on the GR 66 of the Sabaody Archipelago and which is responsible of its security. When the Straw Hat Pirates first arrived there, the Marine Base's influence started at GR 30 and ended up at GR 79, letting the GR 1 to 29 be a lawless area where pirates and bounty hunters ruled. After the Marine Headquarters' location was moved to the New World, the Marine Base's influence weakened and the Archipelago became less safe and more difficult to protect.

Crisis at the Sabaody Archipelago
During the preparation for the Battle of Marineford, the Sabaody Archipelago Marine Base had to protect the Archipelago completely on his own. When it learned that Silvers Rayleigh was going to be sold as a slave, it surrounded the Human Auctioning House with all his troops. After Monkey D. Luffy punched Saint Charloss and the Straw Hat Pirates attacked the Auction House, the Marine Base was ordered to prevent them, the Heart Pirates and the Kid Pirates to escape until Admiral Kizaru came with some Pacifistas. The Marine Base failed as it was completely defeated by the three pirate crews who managed to escape.

2 Years Later
When the Sabaody Marine Base learned that the (Impostor) Straw Hat Pirates were recruiting new members, it sent marines to GR 46 to confirm that they had come back to the Archipelago. After the investigating team "recognized" the Fake Pirates, the Marine Base decided to evacuate the neighbor groves and to send its troops to prepare for battle. The Captain of the Science Unit, Sentoumaru, told a Marine Officer that he was going to GR 46 on ahead, with PX-5 and PX-7, explaining that the Marine Base was too much underestimating the Straw Hat Pirates.
