The primary fire of the enforcer is more potent than the base weapon of previous Unreal games. It hits instantaneously whatever is in your sight cursor, so there is no need to lead shots. The effect of being hit by an enforcer round causes a slight jostling of the target, meaning that continuous hits can disrupt their movement and aim.
The secondary fire is a short three-burst attack followed by a delay. There is a significant upward kickback from the first to the third shot of the burst, meaning that unless the target is huge, or point-blank, your second and third shots are likely to miss unless you aimed low to begin with.
