Q&A: Super heavy weapons

Q: During the Shooting phase, what is the effect of Blast markers upon detachments containing super heavy weapons? Most particularly, detachments that contain only super heavy weapons?

1. Each super heavy weapon should be treated as having a Firepower of one; each Blast marker thus causes the loss of one Death Ray or Anti-tank shots in the above detachments.
2. Super heavy weapons are only considered to have a Firepower of 1 during firefights. There is no mechanism by which Blast markers affect their shooting, thus titans or land raiders may accumulate blast markers while still firing at full effect.

A: a is correct. Each Blast marker stops one super heavy weapon from firing.
