How many main functions does Search and Rescue (SAR) have?

The correct answer identifies that Search and Rescue (SAR) has two main functions: locating missing persons and providing assistance to individuals in distress. These two components reflect the dual mandate of SAR operations, aiming to not only find those who are lost but also to ensure their safety and health once located.

The first function, locating individuals, involves a range of activities including searching specific areas, using technology and manpower to discover where people may be. The second function entails assessing their condition and providing necessary support and medical care, which might include first aid, evacuation, or shelter.

Other options implying one, three, or four functions might overlook the integrated nature of SAR operations or misinterpret the different stages or aspects of a rescue operation, which can be seen as sub-processes rather than standalone main functions. Understanding this dual aspect is essential for grasping the overall purpose of SAR teams in emergency situations.
