A more thorough explanation:

Definition: WMD stands for weapon of mass destruction. It is a type of weapon that is designed to cause harm or death to a large number of people, without distinguishing between combatants and noncombatants.

Examples of WMDs include:

• Nuclear weapons
• Chemical weapons
• Biological weapons

These examples illustrate the definition of WMD because they are all capable of causing widespread destruction and loss of life. They are not targeted at specific individuals or groups, but rather have the potential to harm anyone in the vicinity of their use.
