What brevity term refers to oscillating an IR pointer in a figure eight about a target?

The term "Snake" refers specifically to the action of oscillating an infrared (IR) pointer in a figure-eight pattern about a target. This technique is used to highlight the target effectively without losing sight of its location, which is particularly useful during operations involving precision weapon systems or close air support. The figure-eight movement helps in identifying the target clearly to observers or sensors, ensuring proper coordination and engagement.

Using this method not only enhances the visibility of the designated target but also minimizes confusion among different units operating in close proximity, as the rhythmic pattern of the pointer can be easily recognized and understood. This makes it a vital communication tool in joint operations and tactical scenarios.
