bigger punch than tank guns. During Vietnam, the U.S. often used self-propelled
artillery for direct fire, despite the doctrine that advised otherwise. But
many veterans remembered the effectiveness of direct fire from towed and
Israel and the United
States have been using artillery for direct fire (shooting at something the gun
crew can see, using a sight similar to a sniper scope) more frequently of late.
This is often more effective than indirect fire (where the crew calculates
where the shell will land when fired at a target they cannot see.) This
practice was common during World War II, especially for taking out bunkers, or
for fighting in cities. But after World War II, it was discouraged, because it
exposed the artillery to more enemy fire. Tanks were seen as more suitable for
this kind of work. But the artillery, especially the 155mm howitzers [
While the doctrine discouraged direct
fire, U.S. artillery was always equipped with a sight for direct fire. This was
there for emergencies, when the enemy troops were visible to the gun
crews. Eight years ago, a U.S. Army
artillery sergeant developed an electronic night sight for his units towed
155mm howitzers. The U.S. Marine Corps frequently used their M198 and M777
towed 155mm howitzers for direct fire, day and night. Army airborne units also
use these towed guns. The guns usually hit targets over a thousand meters away, keeping the
crews relatively safe from enemy fire.
The increasing use of artillery for
direct fire has led to units outside combat zones, training for this. The crews
like this. Indirect fire is all work, and never seeing what the shells do.
Direct fire provides instant feedback.
