The male tanks were the rhomboid tanks that had twin sponsons (sp) each with a 6pdr gun. The female rhomboid tanks had machineguns mounted in their sponsons (sp). There were a couple of hermaphrodites in which a 6 pdr was on one side and machineguns on the other. The terms, male & female & hermaphrodite were applied by the British to their rhomboid type tanks only. The later MK VIII, of which over 100 were made in America for our armored corps, had both cannons and machineguns. Male & female was never applied to it.
Other tanks, like the German A7V had a 57 mm gun and numerous machineguns. Ditto for the French tank (not thinking of the tiny Renault FT which had either a machinegun or a 37mm gun) which had a cannon and numerous machineguns.
The British also developed light pursuit tanks like the Whippet which had a fixed turret.
