No. The only armies in the game are Chaos or Space Marines.
Being a necron player, I too wish they were in Warhammer 40k: Squad command.
Only in the multiplayer.
As it stands, no, the rules are severely outdated, though there are rumors of necrons being updated sometime before the end of 2011. If that is the case, then the Necrons will be a viable army to play again.
In the original game, without expansion packs (Warhammer 40,000: Dawn of War), you have the option to play as the Orks, Space Marines, Chaos Space Marines, and Eldar. If you add the expansion pack "Winter Assault" (requires Warhammer 40,000: Dawn of War or one of its standalone expansion to play) then you gain access to the Imperial Guard. The standalone expansion, "Dark Crusade" (does not require Warhammer 40,000: Dawn of War, or Winter Assault to play, but you can only access armies which come with the game) 2 new armies, the Necrons and the Tau, are added. Finally, in "Soulstorm" (another standalone expansion which doesn't require Warhammer 40,000 or any of its expansions to play) adds the Dark Eldar army and the Sisters of Battle. Warhammer 40,000: Dawn of War is stand-alone. Its expansions, Dark Crusade and Soulstorm, are also standalone (Winter Assault is NOT standalone and requires the original Warhammer 40,000: Dawn of War game or one of its other expansions to play). However, you only get armies that you pay for. For example, buying only Dark Crusade and Soulstorm provides you with only the Necrons, Tau, Dark Eldar, and Sisters of Battle. You cannot access the Eldar, Space Marines, Orks, or Chaos Marines, who require Warhammer 40,000 original to play.
If you are serious about Warhammer 40K you can only play Orks.
