Two Patrols

Vs Space Marines

I was fielding my "default" patrol force: Three warriors (Venom Cannon and two Deathspitters, talons, extra Strength, extra Armour), six carapace Genestealers, and three broods each with nine plain Termagants.

Against me was arrayed a devastator squad, a regular squad and a scout squad, accompanied by a Rhino APC.

I attacked out of a cluster of wreckage parts and a fenced enclosure.  My opponent had taken positions behind a ruined chapel, and spent the first turn taking up positions inside the structures. 

This was probably a mistake - Marine powered armour is better protection against Tyranid firepower than any crumbling stonework could be.

The position in the ruins also meant that precious turns were spent moving in difficult terrain (instead of shooting heavy bolters downrange), and the geometry of the ruins meant that the devastator squad's line of sight to most of the field (in particular, the direction the genestealers and warriors advanced from) was blocked, once they got into position.

The termagants did as they were supposed to, and died in droves, both to incoming bolter fire and to close combat; That left the genestealers a clear run to get stuck in and decide the match by doing what they were supposed to - killing everything that moved.

The Warriors' shooting was nothing impressive, as usual, they did little except provide synapse (they did kill the Rhino, eventually).

Win for the Tyranids.

Vs Dark Eldar

In the interest of trying something new, plus being constrained by not using models already off fighting the Space Marines on the next table, I picked a pure close combat force.

My force consisted of three assault warriors (extra Strength, Initiative, armour, Bioplasma, talons and claws, and Leaping), six Leaping Rippers, and a large brood of Hormagaunts - no shooting, but lots of running-quickly-and-stabbing.

My opponents force consisted of a squad of Warriors (with splinter cannons), a pack of Warp Beasts, and a squad of Wyches mounted in a Raider.

Terrain was mostly clear, with two large hills, a settlement and a small wood copse. I deployed out of sight of the big guns, and moved cautiously forward in the lee of the hill.

The Raider advanced, and wounded a Warrior with its dark lance; In retaliation, everything leapt forward at it (only the warriors had any chance of damaging it, but the rest followed along to provide cover and maintain synapse.  If I could bring down the Raider while the Wyches were still on board, I'd have a good chance of reaching the cover of the woods and then on to the Warrior squad.

Unfortunately, even with three S6 bioplasma attacks and twelve rending S5 clawswipes I was unable to bring it down, and the following turn saw the Wyches dismount and charge, in conjunction with the Warp beasts. 

The Raider and the Wyches sensibly targeted the Warriors, who only lasted into the second close combat phase through sheer luck; When the last Warrior died, the Hormagaunts promptly broke and were cut down as they tried to flee.  By this time, there were hardly any rippers left either.

Win for the Dark Eldar.
