You will need 3 nukes, atleast Castle Bravos. Or you can use the stronger B40s and Tsar Bombas.
Don’t use civilian areas.
You can access all forms of human weaponry. Even a Anti-matter nuke. The max level nuke.
You have access to a navy machine gun, which will fire lots of high speed and caliber bullets.
Since you are a Foundation that can contain anything or “everything”.
Anomalous task forces are available.
You can use Rotten Tomatoes.(A joke)
Now who’s up to the test, use your big brain strategies. You can use all forms of anomalous and human weaponry and services.
