Wrecking Wave Serpents once and for all.

People have been asking me how to beat Eldar Wave Serpent spam. With Space Marines, I believe its totally possible. Eldar is a tough nut to crack. Maybe even the toughest. After a discussion with a dakkaite...

Me:
Spam Tactical Marines with Lascannons inside rhinos.
Lascannon Devastators and Calgar using the UltraMarines
Doctrine. Beat him in the alpha strike. I got about 70 marines
and 10 lascannons on the board. Wave Serpent spam has a
hard time killing that many marines.

Response.

"pshhh your kidding right?

1st off, you would do nada vs serpents with 10 lascanons.
maybe one a wreck per turn.
say you go 1st. kill a serpent, and the guys inside. congrats
his 1st turn..... all rhinos gone, at least 2 marine squads
gone.
your secnodn turn, get lucky kill another serpent.
his 2nd turn, half of survivng marines dead.
rest of game, you do nothing.
serpent spam wins."

Me again:
1st off I wasnt kidding. Thats 8 Rhinos on the table with
3 hull points each. How many Serpents does he have to
kill them all in one turn, 9? And to kill a couple squads too?
Being Space Marines, either you go first using the Tac Doctrine and lets say I do kill one serpent. Ok if he goes
first. I only see 4 ws max. He kills a few Rhinos, Once hes done killing 8 Rhinos he still has to kill 70 marines,
60 that are scoring. Even Eldar doesnt have that many shots.
Be realistic.

Here is the list ive been building to give Eldar a hard fight and a fighting chance grudge deathmatch for me.

Ultramarines Chapter Tactics

HQ: Marneus Calgar
He is here to give you plus 1 on either Tac or Dev Doctrine, which ever one you need most at the time. Also he can defend your home objective with a tac squad very well. Orbital Bombardment is a sweet bonus.

This is awesome for putting wounds on units in cover and to shoot at units that just got out of a wrecked tank.

2000 pts

If going 2nd you stay away so he can only shoot the Serpent Shields. And now that his shields are down, you take advantage with TL Lascannons and its AP2.

Going 1st, you get the Tac Doctrine up and give him a nasty alpha strike!
Thats 6 TL Lascannons
4 Lascannons and 8 Hunter Killer Missiles that re-roll 1s.
And of course the game breaking Orbital Bombardment. ( Eldar players need to start spreading out.)

Thats a devastating turn 1.
What do you guys think?
