Bonus Information:
The warband possesses two cargo ships and one frigate, as well as 50 gene-seeds.
The number of deployable Astartes is 22 Space Marines.
For comparison, a tactical squad contains 10 Astartes, and a company roughly one hundred.
Atreus is therefore far from being a Space Marine Chapter with 1,000 Space Marines, and the legendary Legions could reach terrifying numbers.
The Ultramarines numbered 250,000 members at their peak.
As a reminder, Atreus Silver aims to surpass Roboute Guilliman at his height with the Five Hundred Worlds.
