I've got a character who enlisted as a drummer in the British army at the age of twelve somewhere around 1775. I want him to raise through the ranks rather quickly through manipulating his fellow soldiers and sucking up to the officers. So anyway, how old should he be when he makes sergeant?
And, erm, if that's way too specific or confusing, what would the average age of a sergeant in the late 1700's have been?
Thanks a lot, guys! Your help will be appreciated!
