I enjoy the concept, but I have several problems with the mission as laid out. Simplest, the mission has inconsistent formatting within it and at least one major typo. Further, you don't provide a default deployment setup and instead direct people to the Advanced Rulebook, which not everyone will have. I also have issue with the way you describe seizing objectives - requiring base contact isn't awful, but the rules as written do not require enemy units to be far enough away from the objective. What happens when two models, one from each army, are touching the objective on opposite sides?
