  • Reasons I can think of for the size:

    1. Ammunition is large and needs to be stored carefully so it doesn’t explode. And this thing will either need extremely heavy batteries, or carefully protected tanks of fuel onboard - or both. So that’s going to massively add to the weight.
    2. Human beings are soft and squishy. We’d need huge amounts of suspension for the purpose, plus the matter of armor. Think about how large a jet plane really is, or a tank.
    3. Physical laws around mass and movement. Tanks are as small as they are because treads are effective at transferring torque and creating linear acceleration. If they were just on wheels, they would need to be larger. Legs would require huge amounts of mass to safely support the machine, and we’d need to have excellent stabilizer systems in addition to the suspension mentioned above so that you don’t fall flat on your face
    4. Passive cooling (which would probably be necessary for safety - you don’t want a sniper stopping your whole mech by shooting a few fans) requires wide surface areas to dump the exhaust heat.

    That’s all I can immediately justify, but basically, it would have to be huge.
