(Ground attack tactics
By Generalmajor Hitschhold at Kaufbeuren, Germany, and Latimer House, England, 20 September-4 October 1945.):
If the enemy had air superiority, fighter escort furnished by regular fighter units was advisable. Strong fighter opposition forces the ground attack formation to make greatly concentrated mass attacks (usually with approach at great altitude for a dive attack, or on occasion a low level attack with the element of surprise). Effective strafing attacks could not then be flown, because the effectiveness of the ground attack units was thus already cut in half. The most effective weapons of the ground attack F.W.190 were its 2 cm. cannon MG 151 and its heavy MG 131 13 mm. Bombs were less effective.
The weather in part decides the type of mission to be flown by ground attack units and also the size of the formations, i.e. the worse the weather, the smaller the formation. A minimum ceiling of 6000-8000 feet is required for dive bombing attacks. Shallow dive attacks can be flown with a ceiling of 1500 feet and low level attacks with still lower ceilings. Attacks under low ceilings usually result in higher losses, because the anti-aircraft fire cannot be adequately combatted and because the ground attack aircraft are too easily sighted by enemy aircraft.
