A short list of all tanks that currently is missing the Transmission barriers making the direct front of the hull near the transmission more immune to APHE and Spalling.
Strv m/42 EH
Pvkv m/43 (1946) (was removed after the update after they fixed the transmission barrier for the Pvkv m/43 1963 for some reason, probably a error.)
Strv m/40L
Strv m/38
Stay tuned, More on the way.
