So, I played my second game with my guard last night, and my first game with them in 6th ed (my 2nd 6th ed game, overall).

My list:
Lord Commissar (Power Fist, Meltabombs, Close Combat Weapon)
Company Command (4x Meltaguns, Bolt Pistol on Captain), Officer of the Fleet, in Chimera

2x5 Ratlings
6 Battle Psykers, in Chimera

Infantry Platoon
3x3 Mortars (blobbed with Command Squad)
Command Squad with Mortar, Grenade Launcher
2xInfantry Squad, with 1 Grenade Launcher each (run as a blob)

Veteran Squad with 2 Melta Guns, Grenade Launcher

1x2 Valkyries with Multilaser, MRP, Heavy Bolters
2x1 Valkyrie with Multilaser, MRP, Heavy Bolters

Medusa
Manticore
2xHydra

Aegis Defen[s/c]e Line
-----------------------------------
His list:
-----------------------------------
2xFlyrant with Scything Talons

2xTervigon (which he somehow rolled Gate for both)
Lots of Gaunts; at least two squads to start, but they kept getting birthed by the above.

4x3 Hive Guard
Doom of Malantai

2x5 Shrike Broods (not exactly sure how they were armed)
-------------------------------------------
How it went:
-------------------------------------------
No LoS blocking terrain, spare one small building on my side

Diagonal deployment

Original roll was for Heavy Guns Never Tire, but he talked me into re-rolling ("you'll never get me off the objectives", he claimed; in reflection, I'm resentful of this sort of beardiness), and the new roll was Purge the Alien.

He rolled first turn.

He setup along the front edge of the diagonal in gunline style.

I castled up around the small ruin in my DZ, placing most mortars on top of it, and made a wall around it with my Aegis Line, fitting everything inside (this was a grave error).

  • On his first, his Hive Tyrant Vector Struck one unit of Ratlings (in area terrain outside of my DZ), killing 3 and causing them to retreat.
  • One unit of Shrikes assaulted the other unit of Ratlings (likewise in area terrain outside of my DZ), wiping them out.
  • His Hive Guard Destroyed the Medusa and a Hydra.
  • The Tervigons gated next to my lines, birthed Gaunts.
  • In assault, the Tervigons charged into my lines (in retrospect, I wonder if the could do that?), and broke my infantry blob, sending it off the board.


Simply put, the game seemed mostly over at this point.

On my first turn, I:
  • may have killed a few Gaunts and perhaps a Hive Guard or two with the Manticore and Psyker Battle Squad (they rolled AP1)
  • knocked down one Flyrant with a Hydra, causing one wound


On his next,
  • one Flyrant came through my lines after Vector Striking my Manticore (to no effect).
  • Hive Guard killed the second Hydra and the Chimera containing the Psyker Battle Squad. 3 Psykers died in the Explosion result.
  • The other Tervigon birthed Gaunts near my Command Chimera.
  • In assault, the Gaunts popped the Chimera, and had deployed in such a way so that the unit inside was destroyed by virture of my inability to place models.


On my second, it seemed most everything scattered off.
  • The double unit of Valks came in, as did one singleton. They shot at a few things to little effect (e.g. killed a fair number of Gaunts) and did perhaps a wound here or there against Hive Guard or Hive Tyrants.
  • The mortars shot and killed some Gaunts in his gunline, but
  • the Manticore completely scattered off target, even with 3 Barrages rolled.
  • The Ratlings re-grouped, but failed to hit anything.

On his next turn,
  • Hive Guard scored enough sixes to blow up the Valkyrie with the Lord Commissar and Veterans. He and one veteran survived the crash.
  • The Hive Tyrant got into the mortars and killed 4. They ran and were overrun.
  • Shrikes descended upon the Commissar and Veteran, wiping them out.


On my next, the Valks shot at some things to little effect.
The two Ratlings missed again.

Not a fun game; very one-sided.

(Rather brutal) reflections on my list and play:
  • I never fired the heavy bolters on the Valks (for 40 wasted points)
  • I forgot about the effect of the Officer of the Fleet, but his Doom came in so late that it was a moot point.
  • Setting up my infantry between vehicles and an Aegis Line might look cool, but is a terrible tactic.
  • Running an Aegis Line against Tyranids really seemed to do more harm than good.
  • Running a blob squad without a Comissar was quite daft.
  • Riding things in Valkyries is probably not the way to do it, given crashing flyers. Taking advantaged of the open board to somewhat safely do and immediate drop-chuting melta gun suicide run was probably in order.
  • Fielding an infantry platoon but forgetting to use orders is a big mistake.
  • Setting a trasport with one side blocked by a ruin is a big mistake.
  • Not moving a Chimera is a big mistake.
