Space Hulk/Headscratchers


 * According to the Space Hulk backstory, the last time the Blood Angels tried to cleanse a space hulk, 950 of the chapter's 1000 Space Marines died. Other chapters have been wiped out from less significant losses than that (specifically the Astral Knights, who were declared destroyed after losing 700 of their number destroying the Necron World Engine), and the Blood Angels have the added complication of flawed gene-seed on top of that. So how does the Blood Angels chapter still exist?
 * It does make sense if you remove the last zero from all those numbers.
 * The Blood Angels are one of the fist founding chapters, they continue existing because they have enough political clout, being founded by the emperor himself and what not, and prestige to not be disbanded by the high lords of Terra like the Astral Knights, at least that's how i think it works.
 * Do space marines send scouts into the space hulk as well? The standard codex chapter has 1000 marines with a 100 being scouts, this would mean at least 50 of the lost marines would have been scouts.
 * Considering Genestealer's ability to just shred through all but the best armour (and even then, still having good odds) and there being very little space in the corridors of a Space Hulk, why do they send in troops with the largest, heaviest and most difficult to manoeuvre armour they have available?
 * As Genestealers shred through all but the best armour it's a good idea to send those that have the best armour. In addition all kind of power armours increse the strenght of the wearers which means that the armours are not only for protection but also allows the marines to use bigger things easier.
