Dove into the new Astra Militarum era by buying the new "Hammer of Cadia" boxed set - so now I have more armored vehicles than I know what to do with. Thought about making a fully mechanized force to try out (until now, I've always played IG foot-heavy lists), and came up with the following - please feel free to tell me what you think works and won't work:

Astra Militarum 2000-ish pts armored

3 Leman Russ Squadron(HQ) (2XBattle Cannon, 1XVanquisher cannon) (435)
+Tank Commander(HQ)(30)

Lord Commissar(HQ)(65)

3 Primaris Psykers(lv1)(HQ) (150)
HQ:680

Chem Dog Veteran Squad(Troops) (1Lascannon, 3XGrenade launchers)(95)
+Chimera(65)

Chem Dog Veteran Squad(Troops) (1Lascannon, 3XGrenade launchers)(95)
+Chimera(65)

Chem Dog Veteran Squad (Troops)(1Lascannon, 3XGrenade launchers)(95)
+Chimera(65)
Troops:480

3 Leman Russ Squadron(Hvy)(1Demolisher, 2XBattle Cannon)(470)
Heavy Support:470

3 Hellhound Squadron(FA)(Inferno cannon, Hvy flamer)(375)
Fast Attack:375

Total:2005

Commissar is there so the Chem Dog veteran squads can use his L10 - Psykers are there to buff shooting. All will ride with the Chem Dog squads.
