Troopers armed with assault rifles will often seek cover, and are effective at taking down shields, barriers and armour.
Troopers armed with shotguns will try to close in and eliminate their enemies at short range.
On normal, Troopers do not possess any defenses, but they will have shields on higher difficulties. Turian troopers are also slightly more durable than their human and batarian counterparts.
- The assault rifle armed Troopers are able to put down a constant barrage of fire, as their weapon's heat sink capacity means their reload times can be some distance apart.
- They rarely enter close quarters combat and will usually be easy to deal with if unsupported by more elite troops, such as Legionnaires. They use basic infantry tactics such as pinning down the player with suppression fire, staying in cover while coming out to take pot shots, and flanking.
- Shotgun wielding Troopers behave in a manner similar to an Eclipse Vanguard; however, they are considerably weaker and have a tendency to move into open areas, allowing them to easily be picked off. If they do enter close quarters combat they can cause significant damage. However, their weapons have a slow rate of fire, which allows them to be dealt with easily, particularly if they possess no shields, as powers such as Throw or Concussive Shot will knock them over.
- Full Cryo Blast is useful when they are clustered in groups, allowing them to be killed quickly.
- Overall, Troopers are not difficult to deal with if cover is used wisely. Their main threat is that they can prevent a squad putting down effective fire on more dangerous threats such as Legionnaires or Centurions.
- On harder difficulties they will quite easily bring down the player's shields. It is also of note that the turians hold the close quarters role more often than humans.
- Assault rifle wielding soldiers should always be a higher priority than shotgun wielding ones. While the troopers with shotguns can inflict more damage in close quarters, they have a much lower firing rate and range, and more predictable firing patterns.
