StuG III

What time frame are you referring to?

Stug. were used in place of tanks because there was a shortage of tanks. It was not a deliberate decision because of any inherent superiority of the Stug. Thet were making the best of what was available.

I don't doubt that. It's the same reason WWII Germany produced the Marder series of SP AT guns using whatever tracked vehicle chassis were available. It's also why hundreds of captured Soviet T-34s were modified to German standards and then issued to both Heer and Waffen SS units.

The Pz IV Auf A through Auf E produced during 1939 to 1942 had a 7.5cm/24 howitzer mounted in the turret. They were infantry support vehicles. So it makes sense the StuG would take their place when the Pz IV was up-gunned to become a main battle tank.

The PZ IV was not infantry support vehicles were tanks like others panzer, was not issued a special units, the 75 short gun had best penetration of 37 (with AP) with newest HEAT ammo also best of 50/42
 
They did.
French had Char B, USA had M3 medium (Grant/Lee in UK service), Russkies developed SU-85, -100, 122 -152, and ISU-122 152.
Brits also had many CS (= close support) versions of their tanks, with hull mounted 3in howitzer.

Dave just beat me for another reason :)

the purpose of the Stug III in later marks changed from support vehicle to active panzer replacement and if need be AT

pick up a copy of one of the Stug unit histories or Sturmgeschütze vor
 
Pz-III hull and Pak-40 combo was just so balanced, both were masterpieces of German industry.
 
The German StuG series performed the same infantry support mission as the Soviet Su-76 and American M4(105) Sherman. They should be considered artillery rather then anti-tank weapons.

That was the intention in the early short L24 armed Stugs, however since the days formulation of the concept for the employment of this armored vehicle there was some space for the antitank role, Von Manstein was the creator of the concept and wrote this:

Hello Tomo
British CS tanks usually had their main weapon, early on 3.7in howitzer, then 3in howitzer and later, from Churchill V/Cromwell VI onwards, 95mm howitzer, in their turret, only one early Churchill Mk had the 3in howitzer in the hull and then there was Churchill 3in Gun Carrier in which turret was replaced with 3in cannon in an armoured box, but that was IIRC only a proto or limited production vehicle. British CS tanks were not infantry support vehicles, their function was to give smoke and HE support to gun tanks, which had 2pdr or 6pdr guns which had no or poor HE ammo. Later they just have more effective HE/smoke ammo than gun tanks with 75mm gun.

But British had whole class of tanks specially designed for infantry support, from Matilda I to Churchill Mk VIII, the infantry tanks. In essence heavily armoured but slowly moving mg-nets before they got US 75mm gun with good HE capacity, but lost some anti-armour power, 2pdr was excellent A/T gun up and incl 1940 and 6pdr has good A/T power during 42-43 but was inadequate against front armour of Pz V or VI.

Hello CB
most of Sturmartillery fell under artillery branch, those which were organic in Panzerdivs, at least those in Pz regiments in early 43 when they were used as substitudes to non-exist panzers, belonged to armoured troops. Those which were ad-hoc uattached to panzer divs remained in artillery branch. I cannot recall the status of organic sturmartillery battalions of Panzergrenadierdivs.

Well, the Stug replacing frontline tanks in german panzer Div indicates two things:

a) the good and reliable design that the Stug was with a lot of room for upgunning and improving.

b) The bad state of the german tank planification and manufacturing in late war.

The StuG series were excellent inexpensive infantry support vehicles. However they cannot compare with the Panther G, which is what all German armored battalions would have had if enough were available during 1944.
