G-2

G-2 is a Marine Base in the Grand Line.

History
Fifteen years ago, Rear Admiral Kadar was stationed here. It is currently under the command of Vice Admiral Comil.

Up until recently, it had problems with milk supplies and bitter coffee during meetings. However, Ace's actions helped to secure a steady income of milk. The base was also the place of origin for a scout ship bearing top secret information though it was destroyed when set on fire by unknown means. Ace took it as a chance to steal the confidential document that may or may not contain information on Blackbeard, incidentally saving a marine.

Ships
The G-2 base has two known ships. One of them was to keep its bases supplied; due to its non-combative role it only carries two cannons, yet is still called a Marine ship. The second ship was used by the Marines for scouting; it was burned by a fire that was started by pirates. Ace rescued several crewmen and reports on pirate movements.

Manga and Anime Differences

 * Even though Ace's cover story wasn't present in the anime, G-2 made a quick appearence in Episode 490, when the Marines are celebrating for Whitebeard's death.
