Secret societies regularly send fireteam or squad sized units against cryptid lairs. Draft and mobilisation takes place if the agents do not report back. The FSRD has modernised the technique by first sending FIA operatives to investigate. If the agents report a high value target or contact is lost, an FSRD platoon is deployed to capture or neutralise the target. During extreme contingencies a unit up to a brigade in size is mobilised to deal with the threat and the use of all ordnance is permitted, including nuclear weapons.
Open field interceptions favour the attackers as mechanised and air assets can suppress and severely damage phenomena with accurate fire before it comes into contact range. Urban interception, however, is far more complicated and demands top notch preparation. Urban interceptions against the highest level anomalies average a 90% casualty rate.
It is common for anomalous phenomena to produce hazardous matter for self-defence. In ancient times, this form of attack was regarded as magic. Nowadays, it can commonly be mitigated or stopped by the use of NBC equipment, such as suits or gas masks.
