Male Mark V tank showing short 6 pounder gun barrel

The "Male" tank was a category of tank prevalent in World War I. As opposed to the five machine guns of the female version of the Mark I tank, the male version of the Mark I had a QF 6 pounder 6 cwt Hotchkiss and three machine guns. By the end of World War I, tank technology was advanced enough for tanks to be both male and female.
