Allright, looks like the panther ausf. F parts were there, but not yet constructed. It's okey to use the Ausf. F, but that will only mean that the turret will be modified, right? And the SU-14 was indeed meant for fortifications, but this RP won't only have tanks as enemy. There will be infantry and structures to.
And Slypheed, do you mean the T95 (WoT tank destroyer), or the T95 main battle tank?
