General information:

This achievement can only be earned in Spartan Ops, Episode 2, Chapter 3, "Hacksaw (Fortress)" on Heroic or Legendary difficulty. In this Mission you have to save six Marines - three groups of two - and make sure that at least one Marine is alive at the end of the mission to get the achievement. All Marines are invincible until you have saved the last group by eliminating all of of the initial enemies.

Short version:

Use a Ghost to push a Marine all the way down the canyon at the starting point of the mission while he is still invincible (before rescuing the final group of Marines).

Long version:

I did this solo on Legendary and took three different precautions to make sure at least one of my Marines survives in the end. Of the initial four Marines you save I placed three in locations from where they couldn't run around and do stupid things - like dying. ^^

IMPORTANT NOTE: I did this while they were still invincible - meaning: before rescuing the last two Marines.

1. I meleed the first Marine into a gap between the rocks and the weapon/ammo crates at the start of the mission. He got stuck there, but died in the end.

2. Also at the start of the mission I used a ghost to push the second one over the edge. He was trapped behind the little ledge you see, when you turn around at the start. He also died in the end.

3. For the third one I also used the Ghost to push him all the way down over the edge at the beginning of the mission. I killed myself in the process and destroyed the ghost, but he was still alive and kickin' at the bottom of the canyon. He survived.

All three survived the initial attacks of the Covenant until you have to move up the tower and the two Phantoms appear. Marines 1 & 2 were then apparently killed by the Phantoms (Just assuming this, since I didn't see it happening). The only one surviving was the one at the bottom of the canyon, because either the Phantoms didn't notice him down there or he was out of their range. Then I just went on and killed the Phantoms, the Wraith and the remaining enemies and plong: Achievement unlocked.

Hope, this helps you guys out. Please let me know, if you have any suggestions on the guide. =)
