Category:Tanks by gender
The first tanks were armed with two 6 pdr guns in side-mounted sponsons. Soon some tanks were armed instead with four machine guns in their sponsons. The two types were then distinguished by being termed 'Male' for the gun-armed tanks and 'Female' for the machine gun tanks.
The later Mark V tank was also produced as the 'Composite' version, with one sponson of each type. In service these were more commonly termed 'Hermaphrodites'.
