"How exactly is having weapons at maximum going to help the situation?"
—Samantha Carter

Weapons are devices which—as its primary purpose—are made to inflict harm upon or kill other beings, destroy or damage structures, vehicles, or ships, or to alter others' behavior due to the threat of such harm. Each weapon normally has its own purpose and types.

Weapons which are not intended by design to kill are often termed "less-than-lethal" weapons. Most weapons intended to stun or incapacitate fall into this category. Some normally lethal weapons when used with particular types of ammunition or in certain—limited—manners may also be considered "less-than-lethal".
