Sabotage Specialist

ME1: Use Sabotage 25 times

Use the Sabotage ability 25 times to unlock this achievement. Engineers, Infiltrators, Sentinels, Garrus, Kaiden and Tali all have access to this ability. You must target an enemy or object capable of sustaining damage for the usage counter to increment - pretty much every enemy will count, along with destructible crates.
