Note: About 15% of Israelis identify themselves as religious Zionist (’dati’).
...A disproportionately high percentage of religious Zionist soldiers are represented in combat units. That fact, combined with their high motivation on the battlefield, has resulted in inordinately high numbers of religious Zionist soldiers who have been killed or wounded in action.

Do not forget the Druze. They are a Muslim Sect but not insane. Many serve in the Israeli army and are fierce and loyal soldiers. Their religious philosophy is much closer to Israels Hebrew philosophy than classic Mohammedanism. Some are even Generals in the IDF. They are good guys and loyal to their nation of Israel.
I read the whole article you posted carefully, but I didn't see that surprising statistic in it. Do you have a reference for that? That would be remarkable if true.
