For existing automated systems, human control requires an authorised operator to set the pre-programmed parameters for the weapon system’s operation. Authority to activate such systems is given only in full accordance with the targeting directive for a specific theatre of operations, targeting policy and rules of engagement which ensure adherence to international humanitarian law.

The decision to deploy a particular weapon system in any given theatre of operations depends upon the context of that operation. It would be unreasonable to deny our armed forces the option of using the most appropriate weapons (including systems that can be operated in automatic mode) to engage legitimate military targets.

The targeting process, not the weapon, takes discrimination, proportionality and precautions in attack into account. The decision whether to use lethal force against a legitimate military target is made through a rigorous targeting process, the targeting directive for a specific theatre of operations and rules of engagement which ensure adherence to international humanitarian law.

Since 1999, when the requirement to do so under the Geneva conventions additional protocol I article 36 came into effect for the UK, all new weapons, means and methods of warfare entering service have been subjected to a review in order to ensure they are capable of being used lawfully in armed conflict. The UK is committed to upholding the Geneva conventions and encourages others to do the same.

Systems such as Phalanx are part of the multi-layered defence for our Units, which are governed by the appropriate Command decision processes employing Rules of Engagement authorised by the Ministry of Defence.
