I read this about Stuka:
The dive-bomber was a purpose-built aircraft, designed to drop bombs with pinpoint accuracy on frontline battlefield targets. To support their panzer offensives, the Germans developed close air support into an art form and the Stuka was central to this effort. The secret of German successes in this field was the close integration between air and ground units. Stuka squadrons worked hand-in-hand with ground units so they could intervene rapidly at the decisive point of the battlefield. These highly specialist squadrons were in the thick of the action and developed an impressive reputation. The need to fly deep into the heart of battle meant Stuka pilots suffered some of the highest casualty rates in the Luftwaffe, and as a consequence became some of the most highly decorated German servicemen. Hans-Ulrich Rudel was the most famous Stuka pilot and squadron commander of the war. He was also the most highly decorated German soldier of the war, being the only serviceman to receive the Knight’s Cross with Golden Oak Leaves with Swords and Diamonds.
This give the general tactics. Does Variable depiction a special case of the above Stuka tactics?
