ok, here's a new thread.
While browsing news groups i found a very wierd message pointing me to this site:
http://ourworld.cs.com/soundweapon/
this site is quite wierd and deals with government conspiracy as well as unconventional warfare and weapons.
As I searched new ideas for civ units, I found these sections interesting:
"US News 07/07/97: Wonder Weapons"
"Non-Lethal Weapons"
I will continue reading and present summaries and ideas for units in the next couple of days.
