A Kill Marine is an Independent operator, this much we are all aware. In the entry for a Kill Marine it gives quite an elaborate number of reasons and potential story hooks as to the function and use of a Kill Marine. Missions at the behest of the watch commanders, held in secret from their brothers. Investigators, assassins, representatives of the deathwatch and sometimes the wider Imperium, diplomats (with a big frakking gun), advisers, and of course the one man army.
Kill Teams are canonized as being formed typically for singular missions, often being disbanded after completion. Sometimes these teams are together for more than one mission.
The Death Watch of my own little sector of the Imperium operate with watch captains overseeing multiple kill teams. The members are recruited for two decade long terms.
What I did was make the additional career advancements require completion training programs that each of the player characters would have to undergo in order to gain additional designations that open up more possibilities. The training programs are role play opportunities to demonstrate character development.
Why do I mention this? Because not everyone is suited to become a Kill-Marine. I found that out after only two of my players actually made it through the program. They were able to demonstrate the ability to role play a Kill-Marine to the books standards of what they are. Use of tact, wit, diplomacy, and understanding when to apply force.
So these two have earned the right to role play on their own personal missions. Which as a GM I got a slightly bigger workload with them now. In game fluff wise they have sworn an additional two decades with the Death Watch and the Watch Captain has more flexibility with deploying the characters on their own if needed trusting that they will perform the mission. We haven't had the chance yet to really get a mission on with their newly gained status due to the need of having to deploy the full kill team in repulsing a tyranid invasion...
I got few plans brewed up. If you have ever read Dan Abnetts Brothers of the Snake I drew some inspiration from the first portion of that book where a lone space marine is sent to deal with a dark eldar incursion. I thought of kinda of the same concept but with the kill marine being assigned to aid a world under threat from dark eldar raids. There would be a guard regiment stationed on the planet that could be of help. I'm still working on the missions parameters. I was also considering escalating it too and requiring the rest of the kill team to be sent in way later on. But we'll see... tryanids are kinda a higher priority...
