Heres the layout of the board, Rolled Mission 2 Seize Ground with 4 objectives

Karmans won the initiative here's pics of the deployment for each side and the added objective relays

 North end Karmans deployment, Yetis were held in reserve for Deepstrike

South end Cogs deployment, the Cog Infiltrators used scout to deploy near the middle of the table near the objective marker toward the bottom left of the photo

Round 1
Not much happens the first round, All the units on both sides advance and some take up positions around objectives. 

Round 2
Karmens start the round off and roll for deepstrike but fail.

The Karmans King Mammoth unit flies forward and takes aim at the Cog Heavy Mech with its Ion Cannon. The King Mammoth gets 4 shots at the Mech and 2 take some chunks out of its armor.

The Cog Heavy Mech returns fire at the King Mammoth dealing out 5 hits and 1 automatic wound. King Mammoth takes 5 wounds, a Devastating attack from the Heavy Mech.

Saint Anuman runs up behind King Mammoth and lets out a psychic shriek against the infiltrators on the other side of the shipping containers causing one of the infiltrators minds to explode. The Armored Cog then moves closer to King Mammoth and fires off a few rounds into its hull. King Mammoth takes a wound and becomes pinned.

The Kaptars fire its plasma cannon at the Cog Heavy Mech in the distance and get 3 direct hits. The Mech takes 2 wounds

The Cog Infiltrators run out from cover and assault the damaged King Mammoth, using their doctrines they manage 4 hits which tear apart the King Mammoth as is crashes to the ground destroyed.

Round 3
Karmans get a successful deepstrike this round and try to deploy behind the Cog Heavy Mech but roll a 2 so they get sent a bit off course toward the corner of the table.

The Yetis still manage to be within assault range so they rush up and attack the Heavy Mech. The two units exchange attacks and the Yetis deal 4 hits and 1 auto wound to the Mech while receiving 2 hits from the Mech. The Yetis armor protect them from any damage but their powerfist prove too much for the Mech and rip the mech apart, destroying it.

Fearing the same fate as the Heavy Mech, the Cog Shooters fire at the Yeti unit. With their linked doctrines they fire 6 hits but the Yeti armor is no match for their ammunition.

 Saint Anuman moves forward and manifests his psyker abilites letting out a flame breath at the Cog Infiltrator unit burning 2 of the 4 members to ash. He then unloads his plasma pistol at the remaining Infiltrators but the attack fails to do any harm.

The Infiltrators then rush forward and attack Saint Anuman, their power swords rip through his suit and he takes 3 wounds

The Kaptar unit rushes over to aid Saint Anuman

The Armored Cog turns around and unloads a barrage of weapon fire into the Yeti Squad but his attempt fails to do any damage to the Yetis

Round 4
Time is running out, the Yetis move forward to capture an objective and return fire at the Armored Cog. The Cog takes 6 hits but manages to dodge and absorb all of them. The Armored Cog then moves forward and fires his eradication ray close range into the group of Yeti, but they manage to dodge the ray.

The Kaptars move forward and surround an objective marker and then fire at the Cog Infiltrators dealing 5 hits, they Infiltrators take 1 wound.

In a last ditch effort the remaining Cog Infiltrator moves closer to the objective and fires at the Kaptars but the Kaptars are unaffected.

Saint Anuman releases another flame breath at the Infiltrator and fires his plasma pistol but his attack is unsuccessful. The Cog Shooters fire at the Yetis dealing out 6 hits and managing to wound and kill 1 Yeti Soldier. In the end the Cogs take victory by gaining control over an objective and denying the Karmans from obtaining any objective.

Final Thoughts:
I expected the Karmans to win but was surprised by the Cogs. This mission was fun. I played mission 4 sabotage about a month ago with the 40k dark vengeance starter armies and the terminators won it in the last round by deepstriking at the objective and wiping out a squad of chaos cultists (wish I would have taken pictures of that game). I tried to do the same thing with the Yeti squad this time but the Cogs proved to be more resilient to damage than I thought they would be.

If you haven't heard of or played One Page 40k go give it a try, its really great and there is a handful of other rule sets for fantasy, space, football and more that I'll be playing and making future battle reports on.
