On the 13th of May 1942 it was questioned whether the Pz Kpfw II , then in production at the rate of 50 per month was still adequate in a combat role , or whether it should be replaced by the 75mm PaK40 mounted on the Pz Kpfw II chassis.Early in June it was decided to produce 50 per cent of the series as 75mm PaK Sf , and later in the month it was decided that at least 75 per cent (100 per cent if the Army so desired) of all new production was to be 75mm PaK40.Production was cut short in June 1943 to give all the Pz Kpfw II Fgst to Wespe (Wasp) production.From July 1943 to March 1944 an additional seventy-five PaK40/2 were mounted on converted Pz Kpfw II Ausf c , A , B , C and F chassis. The hull and super structure front remained the same as the basic Pz Kpfw II Ausf F.Asuperstructure was built to form a fighting compartment.The upper half of the field-carriage mount for the 75mm PaK40 was retained but modified with girders to form the support for the anti-tank gun.The Marder II was issued to panzerjäer detachments (SP) from July 1942.It remained in active service until the end of the war serving on all major fronts.
