As in a number of these missions, controversies emerged – such as charges that Israelis killed Palestinian children.

CBN News met with those who must answer such charges at a special base that trains troops to fight, both fiercely and morally.

As we saw after 9/11, military combat has moved from open battlefields to mainly urban settings: cities, villages and buildings.

For a better understanding, we met with Israel's Government Press Office Foreign Press Director Ron Paz and a top Israeli general at the Tse'elim base camp near the Gaza Strip.

Here, the Israeli Defense Forces (IDF) built an urban setting many blocks wide and long. It mimics the real locales where they're fighting their main foes in the current era: terrorists and guerilla fighters.

Paz told us, "It's all about urban warfare at the end of the day. There are no more divisions of tanks, one against another, or air forces or ships." 

At one point we walked through an entire simulated Arab city where soldiers can practice. It had everything from minarets to high-rise buildings. 

There's even graffiti of guerilla fighters sketched on many buildings, as if you were in a city where real terrorists live.

“The guerrilla is hiding behind human shields, in places just like that," Paz explained as he pointed to a building with artwork of a hooded terrorist throwing a grenade. "And the challenge: how do you separate between militants who are dressed up as civilians and innocent people who, God forbid, we should want any of them harmed? This is exactly the facility that's supposed to have you trained for that assignment."

Paz insists the troops fighting in Jenin recently were so well-trained, they absolutely caused no collateral damage and killed no civilians. "It was, for sure, the first large-scale operation that ended up with zero civilian casulties," he noted. "And this is remarkable. It's unprecedented."
