A new drone from Israel's Elbit Systems called Lanius combines a number of technologies that put it at the forefront of how drones are transforming war.

At the same time, reports about the drone may raise questions about how this technology may make war more controversial as "robots" play a larger role in it.

The more armies and defense companies invest in new technology that enables combat to take place remotely — without soldiers interacting with civilians, for instance — the more it seems like "robot wars."

Elbit Systems has said that Lanius is "part of the Legion-X robotic and autonomous combat solution." Elbit is one of Israel's three largest defense companies and is at the forefront of defense technology.
