OVERHEAD FIRE AND CONDITION OF GROUND.
During the fighting on the Marne and on the Aisne, guns were often able to support the infantry advance to within 100 yards of the enemy’s position.
Even on flat ground frequent instances are given where overhead fire has been used, with excellent effect, from buildings.
On the whole it would appear that not enough use is made of this fire.
This is a question that should be carefully studied by all Machine Gun Officers.
