Early versions of the Jagdpanzer IV carried two standard (no modification made) [[MG 42]] machine guns on both sides of the main gun mantlet/glacis, firing [[7.92×57mm Mauser]] rifle ammunition through a [[firing port]] which was protected by an armored cover plate (with the MG 42 retracted) when not in use. As the main gun was located between these machine guns one machine gun could be operated from the left side only, which is impractical for [[Handedness|non-left-handed]] operators, and the other one from the right side only. Later version Jagdpanzer IVs carried only one MG 42 as internal secondary armament with about 1,200 rounds of ammunition.<ref>[https://tanks-encyclopedia.com/ww2/nazi_germany/jagdpanzer-iv.php Jagdpanzer IV at Tank Encyclopedia]</ref> The Jagdpanzer IV secondary armament was exceptional, as other World War II era German tanks or other armored vehicles used the [[MG 34#MG 34 Panzerlauf|MG 34]] for internal secondary or co-axial armament.
