Dirty Radium Bomb

"A LOW TECH DIRTY BOMB ON A IRBM ROCKET, LEAVING AN AREA UNINHABITABLE... FOREVER."

The Dirty Radium Bomb is a radiological warhead inspired by dirty bombs.

When the Dirty Radium Bomb lands on a region, that region can no longer be expanded into for the rest of the round by any Superpower, including your own.

Strengths

 * Successfully attacking a capital causes the affected Superpower to lose access to Superweapons.
 * Successfully attacking choke points limits the expansion of enemy Superpowers.
 * Short build time.

Weaknesses

 * Can unintentionally limit your own expansion potential.
