First of all, friendly reminder: there are rules in Covert Operations for hijacking vehicles.
Secondly, when the battle starts, here's how it will work:
- Three Rounds Rapid! Yay!
- Well, technically Four Rounds Rapid. What I will need is a description of what you will do in each of your phases for a single turn (movement, psychic, shooting and assault) so it should be four. Of course, since none of you are psykers and you're facing tau, one of those rounds is obsolete

- Conditional statements are allowed and encouraged (for example, if enough of them died in the shooting phase, then assault, otherwise no action)
Thirdly, a special rule for this game:
- Combat Situation: these Tau aren't tired and bored sentries patrolling a base; they are on a mission and as such they are much more aware. They will start the game with 1 klaxon counter. Also, all vehicles count as inconpicuous for this mission, not just those with a total armour of less than 34
