:Maxim_Gun a owl:Class ;
    rdfs:comment """In 1884 Hiram Maxim invented the world's first automatic portable machine-gun. Maxim used the energy of each bullet's recoil force to eject the spent cartridge, insert the next and fire it. The machine-gun would therefore fire until the entire belt of bullets was used up. 
The Maxim Gun was adopted by the British Army in 1889. It was first used by Britain`s colonial forces in the Matabele war in 1893-94. In one engagement, fifty police of the Rhodesian character company fought off 5,000 Matabele warriors with just four Maxim guns. The design was taken over by the Vickers Company and was used by the army for over seventy years.

The Maxim Gun could fire 400-600 rounds of small-calibre ammunition per minute. Each gun had the firepower of about 100 rifles.
