I'm wanting to create an Imperial Guard Sergeant who was inducted by an Inquisitor. At first he will only have access to the ten-man squad directly under his command. But eventually he will rank up to a Lieutenant and have command of a platoon of 4 squads. I'm planning on using the horde rule from Deathwatch to keep running my squads quick and seamless.
As I've been told, Dark Heresy is rather low-key. I know Rogue Trader is about privateers cruising around in their own ships in pursuit of the almighty Thrones, but would it be reasonable to use it for an Inquisitorial paramilitary campaign?
If you need me to clarify anything feel free to ask. So far my only experience with FFG's games is Deathwatch.
