How to use in your fleet
The actual damage done is based of the energy usage of the target ship and is calculated as follows:
[Base Damage] * [Target Modified Energy Use]
[Target Modified Energy Use] is 1 + ([Target Actual Energy Use] / 256), but always at least 8, and never higher then 30
Don't take the DPS at face-value. The minimum multiplier of Impulse Reaction Emitter ensures that the actual base DPS is twice as strong as Fighters. For any target that uses more energy than 1792, this damage increases slowly until the maximum is reached at 7424. The effective multiplier against such targets is 3.75 (~882K/sec), significantly better than Bombers (cap-for-cap).
Practically speaking, it is better to think of IREs as a specific 'anti-large' fighter (such as Guardians and Golems), as Fleet Ships and Guard Posts don't use enough energy to grant more than minimum damage. The author therefore list their ideal targets here: Golems, Hybrids, Spirecraft, all Neinzul Starships, and to a lesser extent Starships. It is notable that this list is almost entirely optional content and may not be seen by a starting player.
How to counter when in the AI fleet
Countering IREs should not be too difficult using regular fleet-ships and turrets. They can inflict heavy damage against unsuspecting Golems and Spirecraft, so keep your fleet closer together when on the offensive.
