G-2

G-2 is a Marine Base in the Grand Line. It is under the command of Vice Admiral Komir. 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 of a special scout ship, bearing top secret information. It was, however, destroyed by Ace.

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.
