The Panzerkeil was an offensive armoured tactic developed by German Kampfgruppe on the Eastern Front during World War II. The Panzerkeil was developed in response to the Soviet employment of the Pakfront defence.
Usage
The Panzerkeil was an offensive formation used by armoured vehicles, most commonly tanks, supported by infantry and aircraft. The tanks would form into a wedge-shaped formation, with the most heavily armed and armoured vehicles forming the tip. At the battle of Kursk, Tiger Is would form the tip, Panthers the base, with the Panzer IVs and Panzer IIIs forming the wings. The advantage of the Panzerkeil was that the anti-tank gunners of the opposing Pakfront would be forced to constantly adjust their ranges due to the depth of the formation. Also, the heavily armoured Tigers and Panthers would bear the brunt of the anti-tank fire, leaving the more vulnerable tanks safe from enemy fire. The Panzerkeil achieved mixed results. During Operation Citadel, the Panzerkeil enabled the spearheads of Generaloberst Hermann Hoth's 4th Panzer Army to break through the elaborate Soviet defences. Meanwhile, in Generalfeldmarschall Walter Model's 9th Army sector, tank units using the Panzerkeil tactic failed to achieve a breakthrough, and suffered heavy losses due to anti-tank fire. There is also some contention that this formation was rarely used during Operation Citadel due to the scarcity of Tigers and most Panthers being assigned to the Großdeutschland Division. Furthermore, Pioniere had to lead formations to clearmines lest the Tigers be immobilized by anti-tank mines, as the Kursk salient was heavily mined.
Panzerglocke
An evolution of the Panzerkeil was the "Panzerglocke" which was a bell-shaped offensive formation whereby armored engineers would follow the leading heavier tanks, lighter tanks on the flanks and a command group to direct the formation and supporting close-air support. This sometimes was employed with the heavier panzers being surrounded by lighter panzers, the heavier panzers forming the "clapper" of the bell-shaped formation.
