Helicopters with anti-tank munitions did not cause the end of the tank, it just led to the development of better supportive anti-air elements.

Drones with anti-tank munitions is not causing the end of the tank, it will just lead to the development of better supportive anti-drone elements.

Also, I don’t think you could ever “win a war” with just tanks. They always had been and always will be one piece of a broader combined arms system.

No idea, never tried Vegemite. Can’t imagine it being very different though.

Marmite is from the UK. Vegemite is the Australian version.
