Second Game - China incoming

[NDawn]

Apologies first off, this is a direct copy/paste from another forum I post on.

I'm currently having a whale of a time on my second game, upped the difficulty to warlord, yeah I know, soft This time Epic timescale with France, have gone 4 city culture.
Was going to focus solely on culture with minimal military. Sadly the Aztecs declared war on my allied city state, Helsinki, a land locked maritime city state, go figure.
Well I sent along 2 longbow men plus Helsinki's 2 archers and 1 warrior against about 5 jaguars and 4 archers. Thankfully they were being funneled through a choke point 2 tiles wide between some mountains, our archers/longbow men were able to pick them off before they could attack the city. They then sent a few jaguars I think they're their UU round the side to flank, managed to get a swordsman in there in time to fend them off.

As soon as I had wiped out the Aztecs attack China declared war on them and promptly took 5 of their cities. So now I'm building a defensive live in anticipation of an attack, I have advanced scouts overlooking 2 strategic rivers so I can see any approach about 6 tiles out.

Here's some pics, no doubt my improvements leave a lot to be desired. Still not figured out optimal improvement plans.





I have a citadel on the left between the mountain and the ocean, only 1 land tile borders the citadel, once I have my navy up and running protecting the coast this should be relatively easy to defend.

The far right I have 3 land tiles wide so I went :

MOUNTAIN ¦ FORT ¦ CITADEL ¦ FORT ¦ LAKE ¦ MOUNTAIN ¦ OCEAN

Dunno how effective that will be, but if I concentrate my artillery there, I should do ok.

That is where I'm up to so far. I'm building up my military as much as I can afford right now as I know China is going to come gunning for me, through Helsinki I'd imagine. I'm trying to tech to artillery straight off as I feel this would be the best ranged unit for me to have to defend my borders. My only question is what land units would be best in my forts/citadels? I currently have a mix of pikemen/longswordsmen and working to wards musketmen.
