2008 - San Francisco
Kaju, "Godzilla" attacked San Francisco, alerting the world of the global threat of Kaju. As the world recovers, another Kaju hits Japan, then an American Carrier Group. A new world goverment forms in order to protect the world from these monsters, and builds the first of the Jaegers.
Ed Gun was an airforce pilot who fought against Kaju, "Godzilla" in the battle of San-Francisco. He turns to the newly formed Jaeger intitative to help the world fight this threat. After months of training, he is sent to Manila's Shatterdome. As he arrives, the only Jaegers in the world's armament are Mk1 and Mk2 Jaegers, used only to fight off up to Cat 2 Kaju.
So when the first Cat 3 Kaju exits the Breech, the world is horribly unprepared.
