In order to prepare the world for the coming uprising against the hated Imperium, the genestealer cult must utilize every tool in its arsenal to infiltrate society. When that day of ascension comes, members of the planetary military will turn against their own regiments.
On the tabletop, GSC has a special rule called Brood Brothers which allows them to use models from the Astra Militarum faction, a popular Imperium aligned army, as their units. From a modeling standpoint, this opens a lot of opportunities for customization. The best
thing about rules like this is that you can take anything the Astra Militarum uses and steal it for the cult. Is that majestic Leman Russ glorifying the Emperor too much? Deface all Imperial symbols on it and vandalize that thing to kingdom come. Does that aircraft not look like it belongs in your army? Stick a bunch of tentacles and teeth on it to show how corrupted its become.
The amazing thing about this is that all this comes from a single rule in the book. Thats the beauty of tabletop wargaming. Instead of limiting you, the rules open doors for newer more creative ways to model and play. Chaos factions can use Imperial units as long as they corrupt them. If a models weapon is labeled in the rules as heavy improvised weapon then have them whack their enemies with a Space Marine. Its heavy. Its improvised. Its a weapon.
The possibilities are endless!
