angle of depression

To this end, the gun was to have a greater angle of depression than the 8 degrees of Conqueror and better frontal armour.

Grommet wads were used in the same manner as wedge wads for smaller guns when required to fire at angles of depression.

Israeli tanks also had a distinct advantage in the "hull-down" position where steeper angles of depression resulted in less exposure.

The difference of height is computed from the angle of depression or elevation of a fixed point on the staff and the horizontal distance already obtained.

However, it had a significant flaw in that the angle of depression could only be adjusted in a number of large 'steps', making it difficult to aim at certain angles.

Minutes before, he had aligned the four water cannons, training them down at their maximum angle of depression, so now as he locked down the multiple triggers, Sea Witch deluged herself in a pounding cascade of sea water.

Driving backwards away from an enemy is even safer than driving forwards towards them since driving forwards over a bump can throw the front of the tank up in the air, exposing the thin armour of the underside and taking the gun off the target due to its limited angle of depression.
