Mkay, going mostly from memory, I played against Marc last evening, 1850 points he brought his Armored IG, I had my CF, testing some different stuff...
Lord Commissar (2 Plasma Pistols)
Vendetta (3 TL LC, 2 HB)
Vulture (I think, FW flier, TL Punisher Gatling Cannon, HB)
2 Leman Russ w/ Punisher, MM sponsons and LC hull mount
Leman Russ Exterminator (Las Cannon)
Vet Squad (Plasmas, Carapice, in a Chimera)
Vet Squad (Meltas, Plasma? Rode in Vendetta w/ Commissar)
Bane Wolf (MM, Chem flamer)
Line PLT, 3 squads, Commissar
CPT on bike w/Primarch's bolter
Command Squad on bikes w/melta, 3 Grav guns and a Medic
Bike Squad w/MM, 2 Grav guns full squad
2 Scout Squads, cloaks, bolters, snipers, etc... 2 Speeder Storms, 1 MM, 1 HF
Centurion Devastator Squad w/2 Grav Cannon, missiles and split fire
Legion of the Damned
Everything that could combat squad, did. DN rode in the Raven, Bolter Scouts in Storms flanked
So, he got first turn... Set up his 2 Punisher tanks on his left flank, Executioner on far right. Line PLT in the center in a building. I sent my Centurions to my left opposite his Exterminator. Scouts set up in same building and the far Right flank. Had to start the Bike Squads behind cover as well. Reserved the Command Squad and Hunter along with the Legion, Raven and Storms. First turn was my Scouts weathering a LOT of punisher shooting along the way... My turn was the Devastators moving up and wrecking the Chimeras (well, one Chimera and the Bane Wolf) for First Blood.
His Warlord Trait was -1 to my Reserve rolls... So while his fliers came in and helped him collapse my Right flank by killing off the few remaining Scouts there and the bulk of my Centurions, I only had my Hunter come in. My Bike Squads survived by making lots of cover/Armor saves, but are cut down to only a few members each. I charge one Bike Squad into his Vets and hope for the best... The other lasts until next turn, but... So, lots of things die on both side, but I have more reserves so while the board looks sparse for me... I have to get my lads to the field and let them go...
Turn 3, I have 2 Sniper Scouts alive hiding in a Ruin. I think mostly because we both forgot about them. This turn I get the bulk of my Reserves, all but one Scout Speeder (MM one) arrive and it starts to look good for the Marines. The Storm Raven drops the Rifleman off on the way in, then proceeds to fire at the Punisher Tanks... Killed one Tank and damages the other. The Rifleman opens up on the last Chimera and kills it. LoD and Scout Speeder damage the Executioner. Last Biker kills off his Vets and then retreats... To die next turn, but...
Turn 4, his damaged Vendetta drops out the Commissar's squad... The kill off a the few remaining Bikers hanging around and I think somewhere along the line my Centurions die to the massed fire... The Storm Raven and Scout Speeders I think off his now hovering Fliers... To be fair, I think it would not have really mattered had they been Hovering or Flying as the Raven can target 2 with it's array of Vehicle killing weapons and almost guarantee splashing one and potentially both. Coming in late left his Fliers exposed to a Riposte from the Claymore that is a Storm Raven. Was good that his lads deployed from the Transport else when I splash the Vendetta, most of them die. Pretty sure my LoD and remaining bikes in his DZ are killed, but my Scouts and a few other things shoot in and kill off his PCS.
Turn 5 is mostly cleanup, he moves to cover the objective, I shoot him off of it and consolidate. He still has a fair number of lads in his Platoon, but Las Guns are not going to slow down my Command Squad set to crash in and deal with them in HtH... After unloading the rest of my army into them. I do not control the Objective at my Scouts are either in his DZ or have been forgotten and are camping out with a nice lunch started in the original Ruin. Raven kills off his last Tank that has just vaporized my Rifleman... Now, the Raven is completely out of real targets as MM/LC are overkill against IG Grunts, but had we continued, so be it... Over the course of 2 more turns I COULD have gotten the Objective as the one Combat Squad with a Storm woula have been able to Turbo Boost over there and deploy onto it the next turn. Would have been easier to just kill off the remainder of the Platoon though I think...
So, the stars for his side? Vulture with the huge number of shots on Strafing... His Punishers were also quite good, but honestly easier for me to take down. Their weapons have too short a range to NOT play aggressively and so they tend to move beyond their own Support elements and die. His PCS was also quite good, though I think 2 more Flamers might have been good there. They played "Linebacker" and dealt with Deep Strikers coming in. Heavy Weapons in the Line Platoon would have been huge, as it was I could safely ignore that element and deal with the rest. But they did last the game...
Stars for me? Bikes are actually quite deadly now... Making them Troops and Combat Squads means I can saturate the field in Scoring units... They did well. The Raven was amazing. The Rifleman, not so much, but... LoD was "Eh" at best I think. Scouts on LS Storms were really quite good. Flanking and rolling in with a bunch of Bolters and a Heavy Bolter re-rolling 1's to hit is nice... And... Well, the CPT did well, and the Grav weapons on bikes were nice, but highly situational I think. Hunter paid for itself bringing down the then Skimming Flier, and bringing it in from Reserve will I think be SOP henceforth... Overall the Army did well, would have been better as a White Scar force, but...
