What brevity term signifies a FRIENDLY air-to-surface missile launch?

The brevity term that signifies a FRIENDLY air-to-surface missile launch is "Rifle." In military communications, "Rifle" is utilized specifically to indicate to ground forces or other aircraft that a missile has been launched and it is aimed at a target, ensuring that all parties are aware that this action is taking place and that it is a friendly engagement. This helps prevent confusion and reduces the risk of friendly fire incidents, as other units will understand that they are not under threat from the missile launch.

The other terms, while related to military operations, do not specifically indicate a friendly missile launch. For instance, "One away" typically denotes the launch of one projectile, but it does not specify the nature of the launch or its assessment as friendly. "Remington" and "Winchester" serve other specific purposes in brevity terms, referring respectively to the readiness of munitions or indicating that one's armament is depleted, rather than signifying a friendly air-to-surface missile launch.
