Israel, a world leader in hi-tech, is around 30 years away from its ambition of deploying robot forces, and for now will chose between three prototypes of semi-automated armored vehicles to cocoon its troops in battle, defense officials said on Sunday.

Israel has long eyed a future robot army as a means of reducing the use of soldiers on its combustible fronts with Gaza, Lebanon and Syria, just as its air force has increasingly relied on pilot-less drones.

The country draws most of its military personnel from teenage conscripts.
