If you do a play through with Kaiden in the team, you have to complete 40-45 missions with him and Sacrifice Ashley to get this Achievement.

I did Ashley & Kaiden together, before I knew what would happen on Virmire. Fortunately, I'd saved before I landed there, and was able to reload and go do some side missions until Kaiden's came up. I then sacrificed him, and Ashley's came up ever being stuck at the Citadel.

This was the last achievement I needed. I figured it'd be pretty easy because, ya know, Kaiden is the first squad member you get. But no, I did tons of side missions, Feros, Noveria and Virmire and it finally unlocked when the Normandy was being held at the Citadel. Damn near 60 missions! But, now I've got 100% in all 3 Mass Effect games!

Doing Ashley & Kaiden together for my second walkthrough after I did my first one with Wrex & Tali.

Got this after doing all the missions on the Citadel, the main missions (Feros, Noveria, and finding Liara T'Soni), and Asteroid X57. I have yet to get Ashley's achievement, but I imagine I will get it pretty soon, as I'm planning to sacrifice her instead of Kaiden.

Asteroid X57 (the DLC) will provide you with a lot of extra experience for these type of achievements!
