What rotary-wing attack tactic is used during level, forward flight of the aircraft?

Running Fire is a rotary-wing attack tactic employed during level, forward flight of the aircraft. This technique involves the helicopter flying at a relatively low altitude and speed while delivering fire on targets. It combines the aircraft's speed with its ability to stay low to the ground, making it an effective method for engaging enemy forces while minimizing exposure to ground fire.

By utilizing Running Fire, the helicopter can maintain its tactical advantage, allowing for a quick ingress and egress from the target area. This tactic is particularly useful in scenarios where quick engagement and rapid repositioning are necessary. It also allows the helicopter crew to effectively use their weapon systems while on the move, providing continuous fire support without the need to hover in a vulnerable position.

In contrast, the other tactics mentioned would not be suited for level, forward flight. Hovering Fire requires the helicopter to remain stationary, while Diving Fire involves the aircraft descending rapidly onto a target, both of which do not align with the dynamics of Running Fire. Therefore, Running Fire is the correct answer as it accurately describes the tactic used in this specific flight condition.
