These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: Plenty, but the epic Russian folk song "Polyushka Polye" from the main menu stands out in particular.
Fan Nickname: Secret Police General Bao Jin's unique Propaganda Airship is also known as the "Whale" among Chinese ROTR fans. The joke version with meme faces and the Trololo song is commonly called "Trollship".
Good Bad Bugs: Nanobots used by the Manticore Tank get disabled when under the effect of American propaganda leaflets. This has absolutely no effect on the gameplay at all and is so hilarious it was left in.
Memetic Mutation: "Don't get mad, get Grad!" which refers to the GLA Grad's massive amounts of damage even after the nerf.
Hindax, due to stream director Hecthor Doomhammer's semi-obession with the song Hindabuilding. Replace x with whatever.
Moral Event Horizon: The GLA has crossed theirs before the Rise of the Reds story even began, considering that they already nuked Beijing, launched chemical rockets at cities and eviscerated Central Europe in the original Generals/Zero Hour.
Nightmare Fuel: Countless instances in the various story updates. The brutality of the GLA, the European nuclear attacks, the utter moral bankruptcy of the Shock Divisions or the downright grim-dark battle of the Be-Ne-Lux come to mind.
The 7 part mini-series surrounding Orlov's ill-fated deployment to South Sudan contains some rather nightmarish moments, Including brutal GLA ambushes, the effects of toxin shells on infantry and the idea of being trapped in a cooking steel container for hours.
In addition to making some sense of the original Zero Hour campaigns, the intricate description of the GLA insurrection in Germany comes off as pretty scary as well, to the point of marking a dramatic shift in the history of modern European civilisation.
The airborne drop on French Guiana where several Russian planes get fried out of the sky by Wotan Arrays, only for the paratroopers to burn up in the microwave beams or smashed by BM Ds whose parachutes malfunctioned.
