Battle Report: 2K Tyranids vs Tau

This is a test of a new battle report format we're tinkering with. I don't think we really stand a chance at documenting everything, so I'm trying to find a middle ground.

The Mission
The Big Guns Never Tire

The Battlefield
Hammer and Anvil

Turns Played: 4

Tyranids
Victory Points 6

Primary Objectives
1 Captured
4 Contested

Secondary Objectives
Slay the Warlord
First Blood
Linebreaker

Lessons Learned
Perhaps walking the Hive Tyrant up the middle of the table wasn't the smartest thing I could have done.
I underestimated Piranhas.
Hammerheads hurt... a lot.

Predictions for Turn 5
The Tau Hammerheads would have wiped me off one contested objective and a Piranha would have taken me off a second.

Tau
Victory Points 2

Primary Objectives
4 Contested

Secondary Objective
Slay the Warlord
Linebreaker

Lessons Learned
Never forget all of your weapons in your arsenal. I completely forgot each of my three Hammerheads had Smart Missile Systems and never used them. Doh!
Piranhas make great field sweepers against spore mines.
Big Tyranids have plenty of wounds to make them last a long time.

Predictions for Turn 5
Possibly clear The Swarmlord and a Trygon Prime off of my end of the table.
Move into center field with Devilfish and Firewarriors to take center objective.
Piranha and gun drones on the back table side overwhelmed.
