You know what's special about the weapons, and so do I. But I'm not familiar with the rules for using them, and thus have no idea if these concepts would work. So I'm floating the concept to you guys, to see if anyone can make it work.
Idea 1: AC/20 ammunition, .05kt. The 'screw you in particular' or "Taurian Magnum" special weapon.
Idea 2: Thunderbolt ammunition, .1kt.
Idea 3: Arrow IV AA type, 1 kt, low-altitude anti-shipping and anti-squadron air defense.
Idea 4: Kraken MITV, 10 individual 1 megaton warheads, decoys and pen-aids, anti-capital.
Idea 5: Anti-RCT missile, Cruiser-missile 50 body, Peacemaker warhead. "You have officially crossed the red line" alert system.
Idea 6: Advanced special weapons types; pumped-laser antiship weapons, shaped charge or Casaba-Howitzer anti-castle munitions, all the fancy futuretech like nuclear formed projectiles derived from mini-mag orion.
