Turians adhere to a strict moral code: "The needs of the group outweigh that of the individual." Discipline is the foundation of turian society. A turian line never collapses; its troops fall back in order, setting ambushes as they go. You will only see a turian's back when they're dead.
Turians receive the best military training in the galaxy. Their proficiency with a wide range of weapons, as well as their unmatched focus and determination, make up for their lack of speed and agility. They are a redoubtable ally on any battlefield.
With Homing Grenade being the only (and in limited quantity) power capable of inflicting a large amount of direct damage, the Turian Saboteur relies mostly on defensive tactics and weapon damage. As such, he doesn't suffer much carrying heavier weaponry since his other two powers are more situational.
However, being equipped with propulsion packs, the Saboteur has a lot of mobility and is able to effectively switch between camping points.
Since the Saboteur lacks powers to deal with shields, anti-shield weapons (such as the Acolyte) and/or ammo equipment are advised.
The Saboteur's heavy melee attack actually deals Tech damage. Coupled with its decent range and Sabotage's Tech Vulnerability upgrade, a melee attack can kill Centurions and Marauders in a single hit.
The Saboteur has the advantage over geth. Being equipped with Sabotage and Sentry Turret, he can quickly dispose of dangerous enemies like Geth Bombers and Geth Hunters before they pose a threat to the squad, while Homing Grenade can deal with Geth Pyros and Geth Primes with high efficiency.
All enemies but Geth Troopers are protected by shields, so the Acolyte is recommended.
