What's your best favorite weapon in Age of Empires series?

[Ja sa bong]

There are so many weapons which came into play in all of the series in Age of Empires. But if I can think of the one which is my favourite in all the 4 games, the British Longbowmen in Age of Empires II stood out distinctively for me. It's because of their accuracy and long range effectiveness.

Which weapon is your favourite in all the Age of Empires series you've played?
