Spartans, Mongols, and the US Military.
Spartans = Had AMAZING training, and from when they were kids nonetheless. Were an entire state based around military, so it's pretty obvious that they'd have an advanced military for that time. Plus, any 300 people who can fight off a million and kill...I think it was 250K persians? Is BADASS.
Mongols = Some of the most amazing warriors of the time. Emotionless, brutal and savage, they traveled in packs and made no permanent homes. They were a set of badass motherfuckers.
US Military: Even when they were just a militia of farmers and countrymen, they still outpowered the British using Snipers and Guerilla Warfare. They currently have arguably the best and most advanced Air Force, and their Marines are pretty much the best trained in the world.
