Aviram Barkai is a former tank company commander who commanded an armored platoon during the Yom Kippur War. A veteran himself, Barkai turned every stone in his uncompromising search for the truth. To write an accurate book, he interviewed 230 soldiers and commanders and examined endless material, including operations protocols and the Agranat Commission report. The result is On the Edge – a dramatic and compelling book combining the horrors of the first days of the war with the heroic story of the boys riding in their steel chariots.
