Now that infantry has double rank attacks, assuming a rank 7-8 men wide with 3 ranks, how many chaos knights would I need to safely tear apart the front? 7-8? More?

Or should I just go full in on Chosen Chaos Knights with 6 or 7 of them dumping nearly 20 attacks?

Lets assume the enemy is dwarfs with great weapons.

Am I right in how cannons w9rk?

>choose place on field in range
>roll artillery and scatter dice
>this is where it lands

However the rulebook says you measure the artillery dice FROM the cannon?

I've mistaken Tempestus for the Strike Force Justian.
