This template is used to create a break in the article. It is commonly used at the end of a section to make it so that a floated image will not float over the header of the next section. Or just to later start a text under an image (which may be at the top a section), instead of next to it, without having to manually add a number of empty lines.
Usage: {{break}} or {{-}}.
Example:
===Lightning gun===
[[File:lightning_gun.png|thumb|left]]
{{break}}
The lightining gun is an hitscan weapon blah blah blah...
