UK forces, and the wider ISAF mission, have materially improved the security of Afghanistan since 2001. This allowed the developed Afghan national security forces to assume lead security responsibility for their own country from June 2013. As an integral capability of UK forces, remotely piloted air systems (RPAS) are assessed to have made a valuable contribution, both in their surveillance and strike roles, to the improved security situation.
All UK forces operate in accordance with International Humanitarian Law, following the principles of distinction, humanity, proportionality and military necessity. The UK’s clearly defined rules of engagement, which cover the use of RPAS, are formulated on this basis.
