cool new unit

Hey, I was thinking it would be cool if there was a unit like a mercenary. Unique fast-moving infantry for some Arabian civ that could also mine gold and faster than vils, kind of like dwarves from aom. Cuz there's nothing a mercenary loves more than gold! Or maybe a pirate?

Would cost a lot of gold because it could be used as an investment , but might pay for itself in the long run. Wouldn't be too bad against trash tho. Civ could be Sassanids?

Also kind of fits into the new trend where unique units have some wacky new quirks and this one would have it too but it wouldn't really stray from aoe roots.
