But decorating isn't really your thing. What is a Commissar without at least a regiment's worth of guardsmen to corral?
You're aboard the flagship of the Lord General's battleforce, the grand cruiser
Crucible of Justice. The fleet is en route to some crisis zone or another, but you're somewhat outside the regular chain of information. The Lord General has summoned you to his office, hopefully to give you a role to play.
"The biggest threat facing the sector at this time isn't marauding xenos," he begins, rolling his eyes, "Despite the presence of that tyranid hive ship, the Navy assures me that it was a lone survivor of a splinter fleet. Time will tell whether that is an accurate assessment. No, it's a more mundane threat facing the Imperium this day.
"Rebellions are becoming more fashionable than usual in this region, and we've been directed to put them down with all haste. So far it appears to be standard discontent and politics, but it's very possible there could be external influence at work here. If stability is lost, we could see all manner of threats taking advantage of the confusion. Piracy is already on the rise, and the last thing we need is the Tau stepping in to preach their 'Greater Good'.
"I don't usually do this, but you've distinguished yourself sufficiently. I'm offering you a choice of two deployments.
"The 203rd Verdian have a good fighting record, low instances of trouble from them. They're accompanying the main force to Eumea along with several other regiments. The planet is at risk of being lost entirely, the PDF has proven itself... unreliable. It's one of our first combat zones, and with good faith the first of many easy victories. They could certainly use a skilled Commissar such as yourself, but they've done well enough without one. You're sure to see action, at the very least.
"The 101st Mettite are on a very different mission. They're new and unproven, which is why I've sent them away from the campaign path. The Adeptus Mechanicus are operating archaeotech digs on Oram-Okbod and they're complaining that they're at risk with the increased conflict. I am of the opinion that they're completely safe, but I'll patronise them if it means their support in future. I imagine you'd spend most of your time liaising with techpriests and disciplining bored guardsmen, but it's an ideal way to learn your role while beating them into shape."
