What was the best Military force(and Battle) of all time? *Edit*

[KungKras]

One of my favourite battles is the battle of Breitenfeld 1631. When Gustav II Adolf showed the potential of the military innovations he was implementing.

I also like the Second Arab Siege of Constantinople, because it reminds me of helms deep, or minas tirith. It's also so random, that a Bulgar army marched in thinking "let's fuck those byzantines up" and then ended up saving Constantinople from the caliphate.
