Hello everyone,
大家嚎， 

I am back with a couple more pictures of StuG IV. The vehicle description reads:
我带着四突的更多图片回来了。车辆的描述如下： 

“Based on the proposal of Ministry of Arms, in February 1942, Krupp design bureau started testing the installation of reworked StuG III superstructure on the new chassis of Panzer IV Ausf.H and J. First vehicles were mass-produced in December 1943, by January 1944 Krupp completely switched to their production from the Panzer IV. In total, 1108 vehicles were built, 31 more were made by converting existing tanks.”
“基于武器部门的要求，在1942年的二月，克虏伯设计局开始测试针对把重制过的三突战斗室安装在四号H型以及J型底盘上的方案。第一辆车在1943年的12月进入量产，在1944年1月，克虏伯就把自己的生产力量完全切换到四号坦克的生产上了。车辆总计制作了1108辆，还有31辆是通过改造现有坦克生产的。”

Comparing the vehicle with the elite StuG Ausf.G obviously makes no sense, since the elite StuG has the (unhistorical) 75mm L/70 (this gun did notfit the classic superstructure – an alternative project existed with the superstructure significantly reworked, but that was not the Ausf.G), so I will be instead comparing it to the “middle” version of StuG (second gun, everything else elited).
把这辆车和三突G的完全体拿来比较是毫无意义的，因为完全体的三突G型有（非史实的）75mm L/70炮（这杆炮塞不进原来的战斗室—有一个要把战斗室大幅度改造的备用计划，但是那个不叫三突G），所以我就把三突G的“中等”版拿来比较（第二杆炮，剩下的都是顶级的） 

The numbers are for 100 percent crew, the second number in brackets belongs to StuG Ausf.G (numbers are for 100 percent crew).
数据都包含了100%乘员的加成，括号中的数字是三突G型的（同样含有100%成员加成）

As you can see, StuG IV is – apart from armor – clearly inferior. Its mobility will almost certainly be worse (despite better terrain resistance) and its gun is generally inferior as well. While both vehicles will likely have good camo factor, notice that the StuG IV gun has a muzzle brake (unlike StuG III top gun), which means it will generally demask the vehicle more after it fires than the top gun of the StuG III. Gun traverse is also not very good, but sufficient.
如你所见，四突—除了装甲以外—都很差。它的机动几乎是比不过三突（除了地形阻力更好一些），主炮也没三突的好。这两辆车的隐蔽应该都不会差，但是要注意四突的炮上有一个炮口制退器（不像三突的顶级炮），也就意味着这辆车在开炮后会比三突的顶级炮更加容易被发现。主炮的射界不是很好，但是够了。
