How convenient it would be to have tanks that could
A) do their bit on the battlefield and also
B) de-swarm (if I can say that?) to go
through/around/under obstacles to get to the troops
behind?
Wait no longer, currently prototyping little swarmable
tanks with a short piece of barrel,
which in swarm-mode
connects together (like that busy lizzie gun) to take on
armour.
In de-swarmed mode the mini tanks separate as needed
and the highly sharpened match-sticks can give a nasty
jab.
In the pipeline is a way to remotely recharge the mini-
tanks. It's kind of 50/50 at the moment, Tesla recharging,
or just a human crew pumping hydraulic fluid to rewind the
rubber bands from a safe distance.
