I was thinking that surely the gunner of the heli should be getting more kills than the pilot right? As things are right now, the pilot is the one who's racking up majority of the kills and the gunner is there to either clean up stragglers or to hit tunnels which the pilot might have missed. I think part of the problem is how terrible the gunner's weapons are. The pilot has 21 Hydra rockets which have a large blast radius, perfect at taking out tunnels or large clumps of infantry and 950 rounds turret with impressive accuracy, rate of fire and splash damage. Both of these weapons do an excellent job at dispatching both tunnels and infantry.
By comparison, the gunner has a grenade launcher and a Gatling gun. The grenade launcher definitely has a better splash than pilot's turret, however, it is tricky to aim (as you have to lead and compensate for projectile drop) and runs out of ammunition far quicker when spammed. The Gatling gun has zero splash damage, so if the helicopter isn't stabilized, good luck hitting anything with it. Most of the pilots I've seen (myself included) aren't too concerned with flying "for the gunner" because it is much more dangerous and less efficient.
So while it may not be very realistic, I'm suggesting swapping the Gatling and nose turret controls. This will encourage more communication between the crew and it will increase the skill ceiling needed to operate the chopper efficiently.
