Machine-Gun

Machine-guns are rapid-firing guns. They include maxims and gatlings.TT

Gatlings
Gatlings were a type of machine-gun with multiple (usually six or ten) barrels. The barrels would revolve; As one barrel was loaded, another would fire and be reloaded.

The system was quite complex, very expensive, and rather heavy, requiring a light artillery carriage to move.

Some gatlings were mounted on airships or on naval vessels, particularly armed freighters for protection from frigates. Humerland's Royal Elephantry Corps actually mounted gatlings on elephants, quite effective in the Aliturian War.
