A looooonnnnnng front

[cumi]

I usually make a kind of walls from my infantries on the frontlines or borders, where I am not planing to attack, but only for "any case". The wall doesn't has to be all along the border, but like a "banana" beside your border cities. You can add some artillery to this wall, too. This kind of a defence helped me a lot of times. My neighboure civ used to attack the wings of my "banana" and not trying to go behind it and attack my city from back (as I would do). And they can not move on your territory fast anyway.

If I have a tiny border I build sometimes a real wall, depending on if I want them to be able to cross my country or not (because my emprire can divide his empire, or helping me in war with the other civs on the other side of my empire).

cheers,

Get a stack of 40 and you'd be amazed at how few losses you start taking.

I fully agree. Two artillery units will bring a veteran infantry unit in normal terrain down to 1 hit point (The AI will not attack with only one HP, and the units will be easily defeated with cavalry). If you have decent cultural borders, just let him throw whatever he's got at you

(Remember: The bombard range of artillery is 2)

I'll get a screen shot of the map soon.

My modded marines are in between tanks and infantry, not as good on attack as tanks, and not as good on defense as infantry. But Better on the attack than infantry, and better on the defense then tanks.
