[Jpost] 2014 was a turning point for the IDF in its battle against Hamas' tunnel systems. Here's how they managed to attack the Gaza Strip with such precision during Operation Guardian of the Walls.

The tunnels were dug by hand and jackhammers, as heavy machinery was out of the question – it would have attracted too much attention from the drones constantly hovering in the skies above.
