-i am a long time necron player who generally had distain for the tau. with the new markerlight rules, i figured that tau might be worth a shot, so here is my experimental list.

HQ
-shas'o, plasma rifle, missile pod, HW multi tracker, shield generator, stimulant injector=142

Elite
-3 crisis suits, plasma rifle, missile pod, multi tracker=186

Troops
-12 firewarriors, devilfish, decoy launchers=205
-12 firewarriors, devilfish, decoy launchers=205

Fast Attack
-8 gun drones
-12 pathfinders, devilfish, decoy launchers=229
-12 pathfinders, devilfish, decoy launchers=229

Heavy support
-hammerhead, railgun, decoy launchers, multi tracker, burst cannons=165
-hammerhead, railgun, decoy launchers, multi tracker, burst cannons=165
-3 sniper drone teams= 240

-total= 1849

-The shas'o goes with the gun drones. he doesn't join their unit, but they surround him so he cannot be shot or charged.

-the drones and shas'o go up one flank, and the crisis go up the other. the firewarriors go up the center and FOF. the pathfinders fly around and markerlight stuff, and the hammerheads provide anti tank/ light infantry support. the sniper teams sit in the back as supporting fire, and also markerlight stuff.
