That January day in Khan Yunis started as another clearing operation. Ben-Simon's reserve unit, Battalion 630, was searching a mosque when they discovered something alarming - an illuminated tunnel with fresh concrete blocks.
"We saw electrical wires and suspected explosives," he says. "My partner and I told everyone to back away. The team that went upstairs survived. We were standing above the tunnel waiting for orders when the charges detonated."
The blast killed Battalion Commander Lt. Col. Nathanel Alkobi (36), Deputy Company Commander Maj. Yair Cohen (30), and Communications Officer Staff Sgt. Ziv Chen (27).
Ben-Simon suffered the worst injuries among the survivors. After nine months at Ichilov, dozens of surgeries, and missing 8cm of shin bone, he maintains remarkable optimism: "I'll celebrate my second birthday here in hospital, but thank God I'm alive. I'm grateful for that every day."
