Which rotary-wing attack tactic is performed when the aircraft is stationary or has little forward motion?

Hovering Fire is the correct answer because this tactic involves the rotary-wing aircraft maintaining a stationary position or very minimal forward motion while engaging targets. This stationary position allows the aircraft to maximize its firing accuracy, take advantage of its weapon system capabilities, and maintain a visual on the target without the challenges of moving quickly.

In this position, the pilot can carefully control the helicopter's altitude and orientation, effectively utilizing weapons such as rockets or machine guns accurately aimed at the target below. This is particularly useful in scenarios where precision is essential, such as in urban environments or when engaging high-value or time-sensitive targets.

The other tactics mentioned serve different operational purposes. For instance, Running Fire involves the aircraft flying at a higher speed while firing, allowing for increased mobility and the ability to evade enemy fire. Diving Fire requires the aircraft to enter a controlled descent toward the target, leveraging gravity to enhance the firing effect but not allowing for the same level of precision as hovering.
