Not to be confused with the XCOM 2 Grenadier class ability.

Holo-Targeting is an ability of the Heavy Class in XCOM: Enemy Unknown.

Shooting at or suppressing enemies also confers +10 Aim to any allies' attacks on those enemies.

– In-Game Description, XCOM: Enemy Unknown


Holo-Targeting works well with a more mobility-focused squad or fire team and encourages focused fire to bring down tough targets. If the player has multiple Holo-Targeting Heavies in a squad, it is possible to stack a large Aim bonus on one target. Holo-Targeting's usefulness is especially highlighted when used in tandem with the Danger Zone ability, which causes suppression to affect a small area around the target, which can result in a + 10 Aim bonus to an entire group of enemies.  This can be combined with a second, or even a third, Bullet Swarm heavy for absolutely devastating results.  

As a rule of thumb for tactical planning, every two applications of Holo-Targeting (10 + 10 Aim) will allow subsequent shooting to "ignore" one level of cover (20 Defense).  

If given Holo-Targeting, a Heavy should typically fire first in all engagements, ideally at enemies in cover or in the distance, with the intention of making follow up shots by other classes easier. This can include allowing Assault teammates to score hits beyond the normal limits of a shotgun's ranged capabilities.
