Were you both on the same xbox? This achievement is not unlocking for Warthog passengers playing Campaign Co-op through Xbox LIVE.

Cheers for the kind words Asturgis!
I've published quite a few guides and have learned what works/doesn't work - and came up with a unique set of fragmented info with colours and tried to keep it uniform throughout.
Campaign/Infinity, Solo/Coop, Difficulty, Online/Offline...
I don't like reading long paragraphs in guides and having to search for such info within. That's just my preference/style though.
