The Britons

The Britons

The Britons are hands down the best ranged unit civ in the game. They
have, however, one of the worst start offs, as other civs build faster
and their scout is easily killed. Once a Brit is fully established
though, he is virtually impossible to stop. Your offense should revolve
around Longbow men, trebs, and maybe some onagers or cavaliers, but
primarily trebs and longbow men. You will want to make your enemy
regret building castles with about 10-15 trebs. That many will take
down a castle in less than 10 seconds. As for longbow men, a decent
swarm is 60, although I prefer 80. With this many, most units won't be
able to even touch the longbow men, as their range is superior to
anything else in the game besides trebs.

As for your start off, you're going to want to make halberders and
champs, but don't make them take up too much of your population limit,
so consider sending them off to die at your enemies base, but slowing
any attack he might send at you in the process.

If you're facing a Brit, an early champion rush can work wonders, as
few Briton players make cavaliers. Other than that, mass onagers and
skirmishers, but don't expect the counter to wipe them out, as longbow
men in large numbers can be difficult to kill with anything you use.
