C$)$ SOG's deployment to both domestic and international anti$-$terrorism efforts will generally displace its deployment to disaster and humanitarian efforts

D$)$ SOG's deployment covers, at all times, both domestic and international anti$-$terrorism efforts as well as disaster and humanitarian operations

E$)$ whenever SOG is unable to deploy to disaster and humanitarian operations, it will be able to deploy to both domestic and international intelligence$-$driven and anti$-$terrorism efforts
