10. Rocket Launchers
Also in the category of “strong enough to reach Seoul,” the 240 mm rocket launchers operated by North Korea are legit weaponry. What’s scarier than the 240 is the 300, which North Korea has been using to upgrade their rocket launching game. With a range of up to 120 miles, versus 40 with the 240 mm, the 300 mm rocket launchers can hit most targets in South Korea.
