Read the protection bar

Shields, biotic barriers and armor are different defenses. Removing the outer layer makes a target easier to control; an enemy that resists Pull is not necessarily immune once its protection is gone.
| Defense | Useful counter family | Reason |
|---|---|---|
| Shields | Overload or Disruptor Ammo | Tech damage attacks electrical protection |
| Barriers | Warp or suitable biotic damage | Counters biotic protection |
| Armor | Incinerate or armor-effective weapons | Damages hardened targets |
| Unprotected health | Pull, Singularity or weapon damage | Control becomes easier without protection |
Combine a primer and detonator
Power combinations require compatible effects in sequence. Pull followed by Warp is a straightforward biotic example on a vulnerable target; ordering both attacks together is more reliable than firing them without watching the target.
| Threat | Response | Watch for |
|---|---|---|
| Cerberus engineer | Interrupt or eliminate early | Deployed turret pressure |
| Guardian | Flank or exploit the shield opening | Shooting the shield wastes time |
| Husk | Control before it reaches cover | Groups can force Shepard out |
| Atlas | Use cover and concentrated damage | Nearby infantry can flank during the duel |
Separate dangerous enemy roles
Cerberus engineers, shield-bearing Guardians and charging husks create different problems. Destroy a turret threat or control a flanker before spending a long burst on the largest distant enemy.
Use the power wheel for coordination
Pause to inspect the target, choose the intended squad power and keep a follow-up ready. A power that is recharging cannot supply the missing half of a planned combination.
