This mission doesn't clarify what system it is for. Given the fantasy vibes I'm assuming it's AoF. The changes to force-org are tricky, by lowering the cap it means lots of players who only have one regular army to play with might be unable to play at all. 20% cap means if you have a big favorite model that is too many points, you won't be able to play unless you have a lot of spare infantry to replace it with.
The rules also aren't very clear what happens when objectives change hands; it says to flip a coin when a point is seized, but is a new coin flipped each time it changes hands, or only when first revealed? Do you lose the bonus/penalty when you lose the point, or do you keep it? I think it's meant to be a one-time flip and you keep it until you lose the objective, but it isn't entirely clear.
And finally, the terrain placing says (explicitly) "without restrictions on placement", which seems like an excellent excuse to trap enemy models or captured objectives in between impassible objectives. That could probably have used some restrictions.
