G-23

G-23 was a former marine base, located in the West Blue that was once regarded as the Most Impregnable base in the world, with versatile members of the Marines and headed by renown veterans, including Vice Admiral Chanson. However, during the Siege of Mariejois, G-23 was bombarded and raided by an unknown force, sending Admiral Akainu to investigate and engage in a few people who revealed themselves to be the culprits behind the attack.
