My Army so far in Storage, looking for tips and advice
Here's my army so far. My dad said we could go to the warhammer store nearby this weekend so I'm preparing to play my first game. I'm running Retaliation Cadre and I plan on buying a Breacher Team and Cadre fireblade next.
I have a Strike Team that will be led by my Ethereal, pathfinders with 3 rail rifles and the Recon burst drone, stealth suits with 2 fusion blasters, a starscythe team with burst and flamers who will be with my commander who has a fusion blaster, missile pod plasma rifle(might be swapped for a High Output burst cannon), and cyclic ion blaster. For vehicles I have a Devil fish with the carbines and Hammerhead with a railgun and burst cannons.
Are there any suggestions on how I should play? This will be my first game using T'au besides the one practice round I had with my friends and his guard. Any advice or tips to fight against other factions?
