Research-Armoured Tank

The first of the iconic war machines that we know so well today. Da Vinci's armoured tank offered a completely new dimension to the battlefield, allowing up to eight soldiers to enter the fray under total protection. Armed with an arsenal of 36 cannons positioned around the circular tank hull and moved by the occupants leg power.
An interesting side note is that building the tank strictly as they have been drawn by Da Vinci would mean that it would not be able to move. A brilliant mind like Da Vinci would not overlook such detail so it may be that he had intentionally included this fault, highlighting his hesitation at using his creativity to produce such devastating war machines!
