I keep reading about people doing this Iron Man mode but don't recall ever seeing this option. I started my first game on normal and am playing through that right now and plan on tackling classic after but I feel I too want to be an Iron Man.
When you select difficulty, there is a box marked Advanced Options. Click that, and Iron Man mode will pop up, along with enabling the tutorial.
Iron Man mode gives you only a single autosave file, as opposed to the several you normally have.
Edit: Wouldn't mean anything if you could use multiple manual save files.
Playing normal, I use two: one before starting a mission (in case my squad setup is totally wrong for the mission), and one right at the beginning (in case the mission goes bad very early). --- There are 10 types of people in the world.

Ahh gotcha, I've more or less been iron manning it anyways then, only on my last mission did I restart it after my max ranked sniper didn't make it cause without him I've got no one and my world is on the brink of utter chaos. Will definitely do the iron man on my classic play through though, love the challenge of this game!
I'm only pretty sure, but I don't think you get to save at all while using Iron Man mode. The game should autosave and that's your only save in that game. --- H-He's like a bear! He's like a big shaved bear that hates people! - The Scout
