I’ve seen people on YouTube using honour guard to remove die showing indirect damage. On the card it says remove a die showing damage, showing the melee and ranged symbols. If this is the case can I claim and resolve indirect with the secret facility battlefield, as that also says damage and shows melee and ranged symbols. What I’m I missing here?

Text in parentheses is reminder text. If it says "damage" then that includes indirect.

Sound the Alarm is really good now lol.

Yes. I think the rules are updated to include indirect damage. Just like errata'd cards work even though their card still shows the old text.

We have these in RR 1.6:

Reminder text is text in parentheses that clarifies game text.
It is used to remind players of rules and does not supersede
the rules. - p. 16

Effects which reference a certain symbol showing on a die work
with any side showing that symbol, even if it is a modified side.
Showing damage includes ranged, melee, and indirect damage. - p.21

From now, every old card that says "showing damage" works with indirect one too i.e Honor Guard, Sound the Alarm, Cannon Fodder, Reversal, Heroism, No Mercy and more.
