Look Out for the Little Guys

Look Out for the Little Guys is an achievement in Halo: Combat Evolved Anniversary that is awarded for not killing any Grunts in the level Two Betrayals, on Heroic difficulty or higher. It is represented by a Grunt's face on top of a purple hexagon.

Tips
Attempting to unlock this achievement playing solo is both difficult and frustrating. A far easier method is to play cooperatively and have the other player kill all of the Grunts. In the absence of another person, players can complete the level on another profile leaving their own controller untouched. This also ensures the player does not accidentally kill a Grunt and nullify their progress. If the player has not already earned them, this method can also potentially unlock the Leave It Where It Lay, Standard Operating Brocedure, Brovershield and Brohammer achievements.
