ZiS-30

Fair enough.

The ZIS-30 on page 72 can have improved ballistics for 15 points.

Annoyingly, we're being referred back to page 58 for it.

They might as well have just printed it in the FAQ, in my opinion.

But let's go to page 58.

Page 58, the improved ballistics, it has a strength of 6 instead of 5.

So even though it's a medium anti-tank gun on the ZIS-30, it's actually strength 6.

And so effectively, it's a heavy anti-tank gun.
