OK everyone. I haven’t got a clue about how I could have even come close to have a win in these games. Today I played 3 separate games, all 1250, all Cities of Death.

My Army: Deamonhunters
HQ:
Brother Captain with 5 GK Terminators (BC include Psycannon + 1 Psycannon in unit)
Troops:
Justicar with 6 GK in PA (1 Psycannon, 1 Incinerator)
9 Stormtroopers with Vet and Rhino (Standard load with GL and Flamer)
FA:
Justicar with 7 GK in PA (1 Psycannon, 1 Incinerator)

First Game: Alpha Fire Sweep
Opponent: Iron Warriors

This game ran pretty smooth. I destroyed the primary weapon on his vindicator and then used the termis and GK units to slowly work through his centralized units. Having done this and placed flags in 3 of the 5 building I was declared winner after 6 turns.

Second Game: Gamma High Ground
Opponent: Eldar

This was the start of my undoing. My opponent fielded 4 squads of Pathfinder Rangers(32 sniper rifles????) additionally he had a couple walkers striking Scorpions and a couple warseers. Nothing here concerned me except the infiltrating pathfinders who setup in the primry building and ALL surrounding locations. This then gave him 32 shots hitting on 2 wounding on 4 with auto deaths due to rolls of 5+ giving AP1 hits? How on earth can this form of arm be beat? My opponent indicated it was cities of death giving him an edge, but honestly and open table war woudl have given him the same outcome. Any suggesting woudl be appreciated.

Third Game: Omega Attrition
Opponent: Necrons

Here I felt I had a good chance. No Monolith, No tooled out Lord, no Ctan = win right. Umm no.

Basically his deployment hid his main force from me for the game (all his warriors hidden = no easy kills for phase out. Additionally his single 5 man Destroyer with 2 additional Heavies basically destroyed my entire army with 3+ hits and 2 plus wounds. Honestly, in all my years of playing my Necrons did I ever get the rolls this guy got. Even when I did hit him he generally made the save or wbb. I think I kills 1 Heavy Destroyer, 1 Immortal, and 2 Warriors in 5 rounds of play. he however killed All terms, the BC, all PAGK except 1 and the 2 Justicars and 4 of my Stormtroopers and the Rhino. At that point I had only the Stormtroopers as a scoring unit and conceded the game. Had to leave for home anyways. Here I think I was a victim of circumstance and bad rolls..

Any suggestions of hints on tactics I may benefit from would be appreciated.

I can see a couple of things with this list that I would tweak. Personally, I hate mixing roles. Example: GK squads with a psycannon and incinerator each, or the ST squad with the 'nade launcher and flamer. Why not specialize your squads? I'd give the FA GK squad 2 incinerators, and the walking GK's the 2 psycannons. That way, you are maximizing your firepower; as one squad is walking, you aren't wasting the incinerator shot each turn...instead, you have 2 psycannons shooting. Also, I'd consider picking up another flamer and grenade launcher for the troopers. Again, so you can specialize the squad. I'd also question the use of terminators in a game under 1500 points. For 2 terminators, you can pretty well buy a squad of stormtroopers. Consider using a grand master and buying more troops. If you haven't, invest in a teleport homer on your storm trooper squads. Another good idea is to give the Justicars melta-bombs, and upgrade that rhino to a chimera. Another tip: Use cover to your advantage. When using GK's, any casualty is a significant loss. Hope this helps.
