What is the name of the RAF's operational capability that involves counter-terrorism?

Operation Shader is the operational capability of the RAF that focuses specifically on counter-terrorism efforts. This operation is part of the UK's broader strategy to tackle threats from terrorism, particularly in the context of the fight against Daesh (ISIS) and other extremist groups. Operation Shader highlights the RAF's role in providing air support and intelligence, surveillance, and reconnaissance capabilities to ensure the safety and security of the nation and its interests.

The other options reference different operations. Operation Ellamy was related to the military intervention in Libya in 2011. Operation Shader II does not exist as a distinct program in the context provided. Operation Tempest also refers to a different set of activities used for tackling threats, but not specifically focused on counter-terrorism. Thus, Operation Shader is uniquely positioned as the current name associated explicitly with counter-terrorism operations conducted by the RAF.
