Which tier of units should handle a possible suicide bomber?

The most appropriate choice for handling a possible suicide bomber is that any capable unit should be involved. This reflects the need for a flexible and adaptive response to immediate threats, such as a suicide bomber scenario. Any capable unit can rely on training, situational assessment, and available resources to respond effectively.

This approach acknowledges that while higher-tier units may have specialized training and equipment, the nature of the threat requires a collective response. Consequently, units at all tiers can be equipped to manage such incidents, depending on the situation's demands and the unit's specific operational capabilities. Ensuring any unit is prepared for this kind of response can enhance overall security and reduce risks to civilian life and property.

The idea that only higher-tier units would be suitable limits the response options in urgent scenarios, where immediate intervention may be critical to preventing loss of life or injury. A comprehensive strategy involves empowering all units, ensuring that they operate effectively and can adequately respond to threats like suicide bombers as they arise.
