One of the most important Luftwaffe missions was the support of the army.
These support missions were of two types:
Direct support: bombing enemy troops on the front edge of the battlefield.
Interdiction: bombing the supply troops and reserves behind the front.
Interdiction was more important because an enemy tank is useless if fuel or ammo fails to reach it.

Therefore, intense efforts were applied against enemy convoys that were easy to identify and easier to attack (than tanks or well-entrenched troops).
As the war dragged on the Germans found it more difficult to achieve air supremacy or air superiority. Their bombers became more vulnerable and it became necessary to use fighters as fighter bombers (Jagdbombers or Jabos for short in German).The Germans used the Fw 190 extensively from 1943 in this role, first using the standard A series and later the F and G sub-types.

To attack trucks moving along a road, a flight of 190s flying in line abreast would turn in the direction of the road with the Jabos in line astern.
Once aligned to the road at 50m altitude and 500 km/h and about 2 km from the rear truck, the fighters climbed to 300m to have better visibility and then shallow dived to attack.
One second before the bomb release, the pilot eased up the nose 3 degrees to ensure the bomb would not hit the propeller. The bomb was released, and the fighter made evasive maneuvers and escaped.
The most effective bombs for this attack consisted of containers with cluster ammunition that spread over a large area ensuring hits and great damage.
