81) War elephant are made of ivory and you need to know how to make a good bridge to use them to battle.
Well, that's better than Civ III, where Elephants (Indian UU alternative to Knights)
didn't require access to ivory, and so could be built anywhere in the world. Unlike Knights, which required access to both horses and iron, so there was a good chance you couldn't build them
But anyway:
169) Cavalry has a small chance of being able to break off an attack. But they can never, ever run away when someone else attacks them.
170) Chinese crossbowmen are the only missile infantry able to injure multiple squads of enemy troops simultaneously. No-one else, not even grenaderes, knows how to do this.
171) Riflemen can shoot down fast-moving cavalry with ease, but cannot do the same to bomb-throwing men with big hats.
172) Despite (judging by the Civilopedia entry) US Marines being the only ones of historical note, the Americans don't actually have a Marine Corp, just special forces.
173) The development of Ironclad warships didn't progress beyond the US Civil War.
174) [non-military] Even in a democracy, it is entirely possible to deal with overcrowf=ding in your cities by ordering everyone to not gather food, thereby reducing population by starving people to death. No-one will object, and the survivors will be happy that overcrowding has been reduced.
175) [non-military, and game-specific] Moses was born in Bejing, and invented Theology. In the same year, Christianity was founded in Shanghai.
Well, I didn't know that. Well, learn something new every day.
