In history, the "Mark I" tank was classified as "male" and "female."
The "male" tank was equipped with two 57MM main guns (one on each side protruding from the sponsons), along with four Hatchkiss light machine guns.
The "female" tank was only equipped with six Vickers machine guns.
This made the "Mark I" require eight crew members to operate: a driver, a commander, and six gunners or two artillerymen and four machine gunners, with a total weight of 28.4 tons.
The "Mark I" tank developed by Shire cuts all equipment down to three machine guns: one Vickers machine gun at the front and one Hatchkiss on each side.
Thus, the crew was reduced to five: a driver, a commander, and three gunners.
Joseph and Dejoka felt regretful and suggested fervently:
"Our engine has 83 horsepower, it can probably move 23 tons. But now the 'Mark I' with its crew weighs less than 19 tons, there is an excess of around 4 tons. We can totally replace the Vickers machine guns with artillery!"
