Brink

This achievement requires that you set and detonate a High-Explosive charge. The HE Charge is included in the Standard Soldier Kit - Simply switch to Soldier class at a Command Post (or spawn as one initially - you will spawn as a Soldier if you have not picked a Preferred Class) and you're good to go, no further abilities require purchase.

In order to place a HE Charge, you must hold the X button to interact with a Destruction Objective - usually a bridge, door, or generator that needs destroying. After a short animation, your charge will be set.

Enemy engineers can still defuse your charge! Stay nearby and guard it until it detonates. All HE Charges have a 40 second timer. It will take a single engineer roughly 3-4 seconds to disarm a charge, multiple engineers working in tandem will disarm much faster - almost instantenously.

Destruction objectives can be found using the Objective Wheel with D-Pad Up. Some easily locatable Destruction objectives are:

SECURITY Day 1: Hostage Rescue
RESISTANCE Day 2: Breakout
SECURITY Day 4: Dirty Bomb

On each of these missions (and more), the first Primary Objective is a Destruction Objective.

The achievement will unlock the moment your charge detonates.

This achievement is for setting and detonating an explosive during a mission. To do this, you need to be the Soldier class and have an objective that usually begins with Destroy. Just follow the objective, hold X to plant your charge and help defend it for 25-40 seconds until it detonates for this easy achievement.
