Remotely Controlled Armoured Vehicle

I have always wanted to serve the army, and now I have an opportunity to do it. You must have noticed that a milaitary tank is often big and bulky which adds to some of its disadvantages such as slower speed. These tanks are made such to protect the bravehearts inside.But, what if, there was no one in it? The vehicle could then be made smaller in size, with thinner armour, lighter body and increased fuel efficiency. I am planning to make such a one. A machine which would serve multiple benefits. Though the idea is still on paper, I've planned much of it. For the prototype, I shall be using stem kit as the chasis, an esp32 eye as the computer and the camera. For the gun machanisim, I am still planning ;) When successful it would not only save lives but also add to the power of our army. Remotely controlling such a tank in the battelfield would not require 2-3 men as it does in a normal armoured vehicle, but only one.
