Amid concerns about the Assad government using chemical weaponry against the Syrian people, NATO has agreed on deploying the Patriot anti-missile system along Turkey's border with Syria.
This particular defence system uses radar to detect and destroy incoming threats, including missiles and aircrafts.
It can lock onto a target more than 80 km away and can be fired remotely within nine seconds of detecting a threat.
