The future arrives:
The Israel Defense Forces (IDF) is creating automated kill zones around the Gaza Strip aimed at halting infiltrations by terrorists, arms smugglers and other hostile individuals.
Now in final stages of operational testing, the "See-Shoot" system will add weapons to the network of overlapping sensors already deployed along the approximately 60-kilometer border separating Israel from the Palestinian coastal territory.
Developed by state-owned Rafael, See-Shoot consists of a series of remotely controlled weapon stations which receive fire-control information from ground sensors and manned and unmanned aircraft. Once a target is verified and authorized for destruction, operators sitting safely behind command center computers push a button to fire the weapon.
