Which of the following is classified as a less-than-lethal weapon?

Expandable batons are classified as less-than-lethal weapons because they are designed to control or subdue a subject while minimizing the risk of causing permanent injury or death. These batons can incapacitate an individual through blunt force, but they are intended to be a more measured response compared to lethal options such as firearms or explosives, which can cause severe harm or fatalities. Less-than-lethal weapons serve a critical role in law enforcement and security by allowing personnel to manage situations effectively while adhering to principles of proportionality and restraint.

The other options, such as explosive devices, firearms, and live ammunition, are inherently designed to cause significant harm, which excludes them from the classification of less-than-lethal weapons. These tools are intended for use in situations where a higher level of force is justified and recognized as potentially lethal.
