Combat Engineer

Combat Engineers are a class of Cerberus soldiers introduced in Mass Effect 3. Despite being a support class, engineers draw a lot of fire from front-line combatants.

Capabilities
Offensive

Combat Engineers are armed with a M-5 Phalanx Heavy Pistol, but their primary means of offense is deploying a powerful stationary Turret.

Defensive

Combat Engineers have shields for extra protection. Engineers can also repair the armor of their Turrets and Atlas mechs if they become damaged.

Tactics

 * After taking down a Combat Engineer's shields, shooting and destroying the stored Turret worn on his back will critically damage, or kill him.
 * If Sabotage is available, any Turret the Combat Engineer has deployed can be hacked and turned against him.
 * There is a small window of time while the Combat Engineer is putting down a turret that a player can kill him and take down the Turret at the same time. If this is missed the turret is activated like normal.
 * If you have the M-98 Widow, if you aim for the centre of an Engineer's chest, the piercing factor of the shot can destroy the turret on the back if the Engineer is setting one up. The Widow itself will either inflict critical wounds, or outright kill the Engineer instantly.
 * It's best to take out Engineers quickly as several engineers can with ample time can cause problems. If they can deploy multiple Turrets, they will near-instantly down you.
 * A good combination to kill Engineers is to use a high level Overload to strip their shields, then finish it off with powerful weapons. The M-98 Widow, Mantis, or a well aimed M-6 Carnifex shot can kill them in a single headshot afterwards.
 * Don't forget, Engineers can repair Atlas mechs and turrets if given time.
 * If you are packing biotics, try to set off a biotic combo near or on a turret as the Engineer deploys it. The biotic explosion and kinetic explosion that follows from the turret will usually kill the engineer on most difficulty settings.
 * Killing Engineers is even more pivotal on higher difficulties, since their rate of repair is often faster than your damage output (i.e., they can repair Atlas mechs faster than you can damage them). If playing on higher difficulties, try to single out any Engineers and eliminate them before engaging any Turrets or mechs.
