Editing Warhammer 40,000/Tactics/Tau/Killteam

Tau may have a hard time in Kill-Team, especially if your strategy revolves around Markerlights, however you can take a basic team of 6 Fire-warriors, 3 Stealth Suits, and 4 Pathfinders, with 12 points left, or take a Team of 6 Fire-warriors, 4 Pathfinders, and 2 Piranha's with 22 points left for upgrades, and seeing as even the Tau's most basic troop weapon has a 1 in 3 chance of scoring a glancing hit against AV 10 and a 1 in 6 against AV 11, your greatest enemy will be your generally small Squad size, although Over-watch may be fun, especially with "Supporting Fire"

The unofficial version allows you access to a single Broadside at 50 points, and makes Pathfinders a Special choice, so Markerlights become even scarcer, but it's more possible to make a more interesting, if smaller, team.
