This is from the Red Dawn remake right? Before they changed the chinese to north korean in post right?
The logo you see featured prominently on these posters is that of the People’s Liberation Army, and the characters within the logo (??) mean 8-1 which is the date of the 1927 Nanchang Uprising. It was on this day that Kuomintang and Communist parties first battled (over Nanchang, capital of Jiangxi province) and is recognized as the anniversary of the People’s Liberation Army.
