What brevity term means sighting a target, non-friendly aircraft, or enemy position?

The term "tally" is used in military communication to indicate that a person has visually acquired a target, which can include non-friendly aircraft or enemy positions. This brevity term is significant in operational contexts where clear and concise communication is essential for situational awareness. When a pilot or observer reports "tally," they are confirming that they can see the specified target, facilitating coordination and actions among team members.

The other terms are used in specific contexts but do not carry the same meaning as "tally." For instance, "contact" can refer broadly to any detected object but does not specifically confirm visual acquisition. "Bogey" typically refers to an unidentified aircraft that could be friendly or hostile. "Squirter" designates a person or vehicle fleeing from a location, which is not directly related to visually acquiring a target. Thus, "tally" accurately captures the intent of visually identifying a specific target or position.
