Age of Darkness is a mod set in the historical period spanning the two world wars of the 20th century, revolving around the struggle between the forces of liberty, socialism and reaction.
In Age of Darkness, light tanks are depicted as being somewhat costlier than a tankette, but with better attack, rate of fire and constitution, making them useful for attacking enemy infantry and other light armoured vehicles, but weak against heavy-calibre machine guns and antitank rounds ... as well as other tanks.
The Mk VII Tetrarch was a light armoured vehicle used by Commonwealth forces during the Second World War. Although it was often undergunned and rather weak, it was still nevertheless light enough to be dropped by gliders, making it often useful for airborne missions.
