Jesus... they're trolling you guys, they haven't received them along with us, is that hard to understand that people are pricks and will lie their asses off and even sell their mothers for a bit of attention.
And Wespe for Wehr but don't confuse an artillery piece that's static with a mobile self propelled gun that can freely move across the battlefield to where it's needed, that mobility is the difference between life and death in this game.
It sounds like it could be a really nice feature, but I'd rather have it just re-crew the weapon with just 2 models instead of being fully re-crewed (because for 100 manpower though). Then after re-crewed, they could simply reinforce the other models. It would also be nice for the halftrack to have an upgrade which would allow it to transport small weapon teams such as the mg-42 and mortar. While we're still on the topic, maybe even figure out how to tow larger weapon teams (ex. pak-40).
The only problem I have with it is the constant stunning of the crew, and vet 5 is wayyy too far off for the stun immunity if you ask me,but overall since it's and the ISU 152 nerfs it's still viable if you ask me.
