I knew I was playing against Ork's, hence all the flamers.
Was really impressed with how the free flamers on the Chimera's worked out. Much better having auto hit's that having to roll on
BS 3.
Only added all the power weapons to hold the Ork's up a bit if they got into combat with me. Probably a waste of points in retrospect.
Maybe should have added some Vox casters & a Mortar or two for more ranged killing power.
Above all, quite happy with the list.
Close game, objective based. Guard won.
Got cheated out of my Melta shot's! *Shake fist in the air wildly! Grrrr!* (dispute over vet's shooting from vehicles)
