Stier Castle Outbreak

"The guests of the How I Can Help Make the World Great ceremony, the Berlin Conference and the Ponyville Conference, including some POWs here in this war, are having a huge prison riot all together. Also, I knew that the guests of the Silbervia Conference are doing an outbreak at the same time. Are they using fake surrender for stealing enemy tech? Well, that's just great."

--Su Ji-Hoon, Keynote

The Stier Castle Outbreak is the jail outbreak event in during the USRAC War that the Silbervia Conference guests (who have fake surrender for stole enemy technology) completed make their plan to make jailbreak and steal all of the Belkan Grey Men technology in Steir Castle follow the Operation Keynote.

Only happened in during the late USRAC War that when the Operation Keynote was started,the Silbervia Conference guests were completed use their intelligence-like jailbreak plan since they, Ponyville Conference guests, How I Can Help Make the World Great ceremony guests  and Berlin Conference guests, including some USRAC War POWs being imprisoned in the Stier Castle.

Later, the Silbervia Conference guests make first jailbreak by killing each Grey Men terrorists who were guarding,then they will rescue others,which their allied aircrafts of Grand Alliance can easily rescue.
