Nuclear bombs, chemical, and biological agents, their use and development are governed by international conventions. But these unconventional often invisible weapons feed our worst fears and could well mark the advent of a new era of global terrorism.

The units charged with neutralizing the terrorists have had to update their engagement tactics. They must now act faster and with less intel because they face a battle-hardened well-armed enemy. To help these units, scientists and researchers to develop new equipment to give them the advantage.

International terrorists are willing to die in attacks against civilians and military targets, in response, minimizing the loss of life has become an absolute priority. New technological allies could prove indispensable. Robots: mimicking human senses, detecting threats without being spotted.

With the advent of digital media and the internet, the global war on terrorism has changed. Extremist groups have used these new tools to increase their ability to strike fear. Computer engineers, security companies and scientists are now working closely with police forces and intelligence services.
