For me, Hittite brings me back to my first experiance with AoE... the trial version. Ahh... memories....
Ahem! Anyhow...
I have come to learn a tool rush gives you the greatest chance of defeating the Hittite enemy. A false rush, crippling his economy, but not quite injuring your bronze like a push or rush can, will keep him in his place as well. Getting a fast civ only makes things worse for them. They aren't slow by any means, but their lack of "extras" seems to put them at a small disadvantage at times. I would also like to point out that there is no such thing as an unstoppable civ. (How is it that Shang is the most powerful in the game, no.. wait, it's Phoe, no, wait.. it's Hitt... no.. it's errr....)
Using the right tools and micromanagement, and a bit of patience, can beat the Hittites in iron. That is, if you didn't click diplomacy right off the bat (you deserve to lose). Camels, as ugly and gangly as they are, seem to work pretty well. Ambushes and distractions turn the slow moving army against itself, even when there is HHA around. Attacking frontally with cheap skirmishers (and yes, even a few SC), set up your camels to come in behind the H/HA's, and chaos ensues. The Camel is weak against archery, but the time can be used to destroy the "indestructable" Hittite siege weapons with cav, chariots, and maybe that big fat wad of light infantry. Barracks units are a bit faster than Academy units, and rather disposable. Throwing them at your enemy like a tomato (it's gonna go splat! anyway) can be quite a good distraction. Dedicating his Cats to something he knows he CAN kill will make him vulnerable to things he SHOULD kill.
One thing I've always tried to remember. Never throw "everything" at an Hittite army. It's like a meat grinder. And they are very vulnerable to slashing attacks from the side and rear. Oh, yeah, one more thing...
Hoyoyo.... Hoyoyo.... Hoyoyo....
