Having been a tanker, i am considerably interested in developments in the latest armored equipment.
I am convinced that tanks in the near future will be smaller, and almost certainly, remote operated. Textron for one, has unveiled a new unit which seems quite effective. Low silhouette, modular weapons platform.
Where today's Abrams Mark 1 has 1500 hp and 70 tons, the Textron version is 7 tons and 1600 hp. Being a hybrid, it can sneak through the woods without much of a sound pattern.
