Define the term "reticle."

The term "reticle" refers to a pattern of lines or markings that are incorporated into the sighting system of an optic, such as a riflescope or a red dot sight. This pattern is essential for helping shooters align their aim accurately with their target. By providing a visual reference point, the reticle allows users to judge distances and adjust for variables such as bullet drop at varying ranges and wind effects during their aiming process.

Visual references can come in various forms, such as crosshairs or illuminated dots, and are designed to enhance precision when aiming. Shooters use these markings to focus their eye on the target and ensure that their point of aim is consistent. Thus, understanding the function of a reticle is crucial for enhancing shooting accuracy and effectiveness.
