Does Blitz affect reinforcement units?
For example, if I use blitz will it also affect my Hetzer from my tank hunter reinforcements? Also, does it affect my Stuh, or is that considered artillery?
In T4 there's an improved Blitz ability, what does that mean exactly, anyone know?
Blitz affects all vehicles, tanks, and infantry, artillery is considered a vehicle. Although blitz has minimal effect on artillery because it mainly increases speed and decrease reload(not arty cooldown).
The t4 blitz ability conviction gives you two more uses of blitz for a total of 4, it also removes the accuracy penalty from blitz, and makes the ability last a full minute instead of 30 seconds.
