Marder series were not fully armored. Weak armor protection was provided only for the front and sides. All Marder series had open tops. Some were issued with canvas tops to protect the crew from the elements.

 was captured in large quantities, the decision was made to mate this gun to the Panzer 38(t).

To do so, the turret and upper superstructure of the Panzer 38 were removed and a new superstructure was bolted on to the chassis. The upper structure mounted the gun and an extended gun shield, giving very limited protection for the commander and the loader. Armour protection overall ranged from 10 to 50 mm. The gun, commander and loader were located on top of the engine deck. It had higher silhouette than Panzer 38, which made it more vulnerable to enemy fire.

The now-called 7.62 cm PaK 36(r)

 was rechambered to be able to use standard German 75 mm ammunition, of which 30 rounds could be carried inside the vehicle. Apart from the main gun, there was a 7.92 mm machine gun mounted in the hull.

This tank destroyer was put into production as the Panzerjäger 38(t) für 7.62 cm PaK 36(r), Sd.Kfz.

 139. A total of 363 of this Marder III variant were built from April 1942 to 1943.

Marder III Ausf.H, Sd.Kfz. 138

The next variant of the Marder III fielded the standard 7.5 cm PaK 40 German anti-tank gun on the Panzer 38(t) Ausf. H. This had the engine in the rear of the vehicle (Ausf. H standing for Heckmotor (rear engine), same as Panzer 38. Unlike the previous model, however, this vehicle utilized the fighting compartment of Panzer 38 in the center. Center compartment allowed crew to stay low in the center of the vehicle, lowering crew exposure to small arms fire and fragments. But because of the rear-mounted engine, there was only enough room for two men to stand in the center. Large side armors gave additional protection for the crew. However, the horseshoe shape armor thinly protected front and side only. The rear and the top were exposed. Thirty-eight rounds of ammunition for the gun were carried. As with the Sd.Kfz.139, this vehicle also carried a 7.92 mm machine gun in the hull, of Czech manufacture.

The full name of this variant was the 7.5 cm PaK 40/3 auf Panzerkampfwagen 38(t) Ausf.H, Sd.Kfz.

 138. The production figures for the 418 Ausf. H Marder IIIs are as follows; 243 (including a single prototype) were built new from November 1942 to April 1943. 175 were converted from Panzer 38(t)s in 1943.

Marder III Ausf.M, Sd.Kfz. 138

The last Marder III variant was based on the Panzer 38(t) Ausf. M (with Ausf. M standing for Mittelmotor (middle engine), again armed with the 75 mm PaK 40

 anti-tank gun. In this variant, the engine was moved from the rear to the middle between driver and the rest of the crew. Because there was no engine in the rear, the gun and the crew did not have to sit on top of the engine deck as in previous models. The fighting compartment could be lowered down to the bottom floor level where the engine used to be. This decreased crew exposure, as well as visibility. Unlike the previous two Marder IIIs, the fighting compartment was closed at the rear protecting the crew up to their mid-section. It stayed open-topped. It could only carry 27 rounds of ammunition. The machinegun port at the front was eliminated in the Ausf. M in favor of an MG 34

 or MG 42 carried by the crew. In the previous two models, the commander served as a gunner. However, in Ausf. M, the radio man moved to the rear with the commander and gunner, serving as a loader. Combat effectiveness increased because the vehicle commander was freed from manning the gun.

The
Ausf. M was the variant which was produced in the largest numbers, some 975 vehicles being manufactured in 1943 and early 1944. Its full name was the Panzerjäger 38(t) mit 7.5 cm PaK 40/3 Ausf.M, Sd.Kfz.

The
Marders were mechanically reliable, as with all vehicles based on the Czechoslovak 38t chassis. Their firepower was sufficient to destroy the majority of Soviet tanks on the battlefield at combat range.

The
Marders weaknesses were mainly related to survivability. The combination of a high silhouette and open-top armor protection made them vulnerable to indirect

 artillery fire. The armor was also quite thin, making them highly vulnerable to enemy tanks and to close-range machinegun fire.

The Marders were not assault vehicles or tank substitutes; the open top meant that operations in urban areas or other close-combat situations were very risky. They were best employed in defensive or overwatch

 roles. Despite their mobility they did not replace the towed antitank guns.

In March 1942, before Marder III appeared, Germany already started production of StuG III assault gun with comparable anti-tank capability (StuG III Ausf. F and later variants). These were fully armored vehicles, built in much greater numbers than vulnerable Marder III. Among many German fully armored tank destroyers, also one based on Panzer 38(t) chassis was built in numbers since 1944: the Jagdpanzer 38(t) (known as Hetzer). The weakly armored Marder series were phased out of production, however, they served until the end of the conflict.
