Reality Askew

So I was reading something about tanks and the new types of armor they have to combat the new advances in weapons.  However I was struck by how basic the thought process seems to be, big tanks, bigger bullets needed.

So it got me to thinking, why not a simple projectile that, upon impact, emits a concentrated EMP (Electromagnetic Pulse)?  Since most tanks are fully computerized, this would effectively render it useless, right?  With the added benefit that all of the vehicles communications systems stop functioning too.  So you’ve got a disabled tank that can’t talk to anyone.

Given weapons, vehicles, even airplanes are becoming more remote controlled or autonomous, this seems like a natural progression in weapons.
