Mission 2 Background

After coming back, the Chairman of the RAO (the Republic of AOCode) and the CPAO (the Communist Party of AOCode) AppOfficer makes Radar the vice chairman.

One day, the USW (the United States of Wrongs, including WA state, TLE state, MLE state, OLE state, UKE state, RE state and so on) launches a enormous war at the RC (the Republic of Corrects, including AC province). The RC calls the Kingdom of PC to help, but still can’t resist the armies of the USW. So now, the RC is calling the RAO to help.

To make it still available to AC on AOCode, The CPAO accepts the plan and lets the brave vice chairman Radar lead \(1000000000\) OIers to help. Before setting off, Radar got some information which tells him that actually it’s not the USW who launches the war, it’s someone else. After reading this information, Radar takes it with him, then sets off.

So what would happen in the war?
