Security
Guests are trained with self-defensive skills from security guards, and they, along with the guards, are more well-armed than those in the How I Can Help Make the World Great ceremony. Defensive structures like prism towers, watchtowers, fences, sandbags and machine gun-armed gun towers were built around the Castle of Friendship and the School of Friendship. Due to all of these democratic values, dress code isn't enforced. Also, they have the security of an average democratic nation. Equestrian royal guards, US soldiers, British soldiers, snipers, Changeling Federation troopers, UN peacekeepers, RA2 GIs, NATO soldiers, Mirage tanks, US Navy SEALs, Guardian GIs, Prism tanks, battle fortresses, rocketeers, cryo legionnaires, javelin soldiers with attack dogs beside them, guardian tanks, Crystal Empire royal guards, bat pony guards, griffon guards, hippogriff guards, elite pony guards, United States National Guard members, Regular Army commandos, enraged Inkwell Isle Girls soldiers, US military vehicles (e.g. M1A1 Abramses, Humvees, Bradley IFVs, etc.), Wachbataillon members, K2 Black Panther MBTs and Perfection Doll rebels (wielding WWI-era Austro-Hungarian weapons) are used as security guards for the event. If all else fails, a Machinegun Robot would be deployed. Non-Rubyist symbols are used. Signs that warn guests not to use Rubyist and anti-Rubyist terms are used.
