The Panzerkampfwagen III Ausführung N (Panzer III Ausf N) (Sd.Kfz. Index: Sd.Kfz. 141/1) was the twelfth and final production variant of the Panzer III series. Developed in 1943 after attempts to outfit the tank with the 75 mm KwK40 gun failed, the Ausf. N was instead armed with the short-barrelled 75 mm KwK37 gun with provision for HEAT rounds as a compromise. Although the variant featured additional reinforced frontal armour and sideskirts, the Ausf. N did not perform well in tank battles, as its armour was insufficient to stop the increasingly powerful Soviet and Allied anti-tank guns. Instead, it found more success as an infantry support tank, capable of covering allied infantry and countering artillery and machine gun emplacements. In total, around 700 Panzer III Ausf. N were built or converted from existing chassis, and would serve extensively until the end of the war.

The Panzer III Ausf. N was introduced during the Closed Beta Test for Ground Forces before Update 1.41. As the final variant of the venerable Panzer III, the Ausf. N offers arguably the best firepower of the series in the form of its short-barrelled 75 mm gun. The gun has a very fast reload time and access to HEAT shells that offer consistent penetration over long distances. Although the gun suffers from low shell velocity, the Ausf. N retains the impressive mobility of the Panzer III series, allowing it to close the distance and compensate for the relative inaccuracy. However, as with other Panzer III variants, while its armour is adequate when facing equivalent opponents, it is largely inadequate against more powerful guns in higher tiers.
