What type of force is defined as intentionally used and known to cause death or serious bodily injury?

The correct answer, deadly force, refers specifically to force that is intended to cause death or serious bodily injury. This type of force is utilized in situations where there is a perceived imminent threat to an individual's life or the lives of others, such as in self-defense scenarios or in certain law enforcement practices.

Deadly force carries a significant legal and ethical burden, as its use can lead to severe consequences, both for the person applying the force and for the broader community. Recognizing it as a distinct category is essential in training and policy-making, ensuring that individuals understand the gravity of employing such force and the circumstances that warrant its use.

Offensive force, while also intentionally applied, does not necessarily imply the intent to cause death or serious bodily harm. Excessive force refers to the inappropriate application of force that exceeds what is necessary and reasonable to achieve a lawful purpose, and physical force is a broader term that encompasses a range of force exerted without the specific intent to kill or cause serious injury.
