So I dropped 2 chimeras (at Matt_Varnish's recommendation) and added a 5th Veteran squad. I also dropped the Power Weapons and 1 Plasma Pistol in order to give the first Veteran Squad the Demolitions ability to allow for a potentially devastating first turn multi-vehicle charge and destruction with melta bombs a plenty :)
