Tau V Salamanders, purge the alien 1500 win

I wanted to test some of my methods and tactics so I picked a smaller force than my opponent. Since it was a friendly game I was happy enough to know that I could loose very easily if I messed up at all. I rolled and opted to go first. I castled all my units in the right hand corner and used Shadowsun and friends with the riptides to force my opponent into a cross fire. Straight away Longstrike blew a demolisher tank away and the path finders started killing troops in the open. I moved the riptides up into the middle of the table so I could move them to counter my opponent when necessary. My opponent's HQ arrived in a drop pod (which was glanced to death on arrival) but the unit was incredibly unlucky when it targeted Longstirke with the orbital bombardment and it scattered 12 inches back, to the HQ, 5 were killed out right and one survived thanks to eternal warrior. In my turn 2 Shadowsun and friends deep struck but ended up on my riptide and my opponent placed the unit at the far side of my deployment zone, he forgot the 3D6 movement for her and I was able to get back in the fight next turn when they killed 3 bikes. Longstrike blew another tank off the board and the nova charged iontide annihilated 7 space marines that were out in the open, the other 2 were killed from plasma fire. I got a bit worried when his deep striking assault marines killed most of my fire warriors so I moved the ion tide towards them (and into cover because his grav guns had killed the other riptide and the plasma cannon was slowly knocking off the wounds). Combined fire from the iontide and remaining path finders finished off the 2 assault marines that were wreaking havoc in my lines. Longstrike took aim again and obliterated the dreadnought. At this point the game was over, he only had a few marines scattered throughout the terrain and his warlord failed a charge and was killed by overwatch from shadowsun and friends. Long strike was by far the unit of the game by blowing up 3 vehicles with just 3 shots. I enjoyed having to be very tactful but if the orbital bombardment hadn't scattered and killed most of his HQ unit, it more than likely would have destroyed Longstrike, from this the riptide would have been killed from the dreadnought and razorback.
