Galactic War Games
From FABT
The Galactic War Games is an event where different species (regardless of affiliation to the Council unless declared an enemy of the galaxy) come to together in the employment of military resources in training for military operations, either exploring the effects of certain types of warfare or testing strategies without actual combat.
The most recent Galactic War Games was the 26th, where the Coalition Fourth, Quarian Second and Krogan Eighth fleets met in the Asgard system to test new strategies as well as build cooperation between the races.
