<,< Suggestion; "Colony Lazors idea from Gundam" TWC platforms (Tach Wave Cannon). Two hits instant kills a level one base; moves 5m/s second recharge takes 30 minutes range 20k, bullet radius of 5k, no defense weapons slots, size of a small base. Armor that of a BS, armors enabled.
I believe it would install a new way to wage warfare. None buy-able, only able to be constructed at bases.
Just for kicks I am going to model what one would look like; be back in a few hours.
