B-Snakes

B-Snakes, or Boom Snakes, are the colloquial term for a class of tunneling drone equipped with WMD warheads. They range from 10 to 50 meters long and have a range from 5000 to 100,000 miles, meaning the longer ones can circle the globe several times.

B-Snakes are designed to tunnel underneath enemy cities or next to their underground bunkers and then detonate themselves.

B-Snakes were created because of the decreased efficiency of projectile based weapons of mass destruction.

A single Boom Snake can destroy an entire city, just like any other WMD.

Boom Snakes are not connected to the internet and do not communicate remotely. The only way to access their control panel is in an oxygen-free environment, because it is welded shut and filled with a substance that immediately bursts into flames and triggers conventional explosives inside the snake if exposed to oxygen.
