On the other hand...
Once a Sturmstaffel was in position about 1,00 yards behind 'its; squadron of bombers, the staffel leader would order his aircraft into line abreast and, still in close formation, they would advance on the bombers. At this stage our tactics were governed by the performance of our wing mounted 3cm cannon. Although the hexogen high-explosive ammunition fired by this weapon was devastatingly effective, the gun's relative low muzzle velocity meant that its accuracy fell off rapidly with range-since we only carried 55 rounds per gun, sufficient for about five seconds of firing, we could not afford to waste ammunition in wild shooting from long range. It was essential that we held our fire until we were right up close against the bombers. We were to advance like Fredrick the Great's infrantrymen, holding our fire until we could see the whites of the enemy's eyes.
During the advance each man picked a bomber and closed in on it. As our formation moved forwards the American bombers would, of course, let fly at us with everything they had. I remember the sky being almost alive with tracer. With strict orders to withhold our fire until the leader gave the order, we could only grit our teeth and press on ahead. In fact, with the extra armour, suprisingly few of our aircraft were knocked down by return fire; like the armoured knights of the Middle Ages, we were well protected. A Staffel might lose one or two aircraft during the advance, but the rest continued relentlessly on. We positioned ourselves about 100 yards behind the bombers before opening fire. From such a range we could hardly miss, and as the 3cm explosive rounds hit home we could see the enemy bombers literally falling apart in front of us. On average, three hits with 3cm ammunition would be sufficient to knock down a four engined bomber, and the shortest burst was usually sufficient to achieve that.
