Editing Jagdpanzer IV (section)

==Armament==
===Main gun===
Armament consisted of a 7.5&nbsp;cm main gun firing [[Glossary of British ordnance terms#Fixed QF|Fixed QF]] 75 × 640mm R ammunition, originally intended to be the Pak 42 L/70. Due to shortages, older guns were initially used, the [[7.5 cm PaK 39|7.5 cm Pak 39 L/43]] for pre-production, and the [[7.5 cm PaK 39|7.5 cm Pak 39 L/48]] for the initial production variant. These were shorter and less powerful than the Pak 42, and also carried a [[muzzle brake]].

Installing the much heavier Pak 42 meant that the ''Jagdpanzer'' IV was nose-heavy, especially with the heavy frontal armour. This made them less mobile and more difficult to operate in rough terrain, leading their crews to nickname them ''Guderian-Ente'' ("Guderian's [[duck]]"). To prevent the rubber rims of the roadwheels being dislocated by the weight of the vehicle, some later versions had steel roadwheels installed on the front.

The final prototype of the ''Jagdpanzer'' IV was presented in December 1943 and production started in January 1944, with the Pak 39 L/48 armed variant staying in production until November. Production of the Pak 42 L/70 armed variants started in August and continued until March/April 1945.

===Secondary armament===

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.
