The heavy airplane bombs are "particularly vexing" for air defense systems built to strike lighter targets.
Hi-tech air defense missiles are designed to strike more lightweight targets and are ill-equipped to counter the bombs' old, heavy iron construction.
This makes them a weapon that the latest air defense systems, like the much-vaunted US Patriot missiles, were not designed to combat, military experts say.
The distance from which you can strike the enemy is low, forcing aircraft to fly into the danger zone of the enemy's air defense systems.
They can reach a target of 30 miles away, out of range of most of the air defense systems on the frontline.
