Nothing new?!?! For shame! A turret-less AFV for starters. The Pzr III chassis for easily adding the Pzr II J. Oh, and maybe one of the best things about adding the StuG III would be adding another EW tank if the short barreled 75mm was made available. There was almost no change (or rather very little) to the chassis over the length of the war, just the gun. There were over 9400 of the StuG III's built. HTC could easily offer 2 types of main guns (7.5 cm StuK 37 L/24 for EW "A/B" version and 7.5 cm StuK 40 L/48 for the LW "G" version).
As so many before me has stated, you want a stug? up a Panzer IV and dont move your turret. theres your stug. wish granted.
Plus we already have a turret-less TD. (M3 TD).
Like i said, it brings nothing new to the game. not saying it shouldnt be added. i'd just like more important things to be added in its place. like say, the m3 lee. that tank is LONG overdue to be added.
Besides, i dont think the G model would qualify to be added to EW. Wiki has its Entrace date as December 1942, thats pushing the limit of EW arena's timeline. so ether, it wouldnt be added, or it would be added but have a perk limit, in which case no one would use it simply because there aren't really any major EW tank battles to begin with.
Id rather have the Panzer III before the stug.
