for grunts you must have 4 non-specialists per every one specialist.with a maximum of 12 regulars and one Squad Leader (who counts as a non-specialist) you can have up to 3 specialists (whichever up to their individual type limitations) The maximum size of a Regular Squad is 16 models. 12 regulars, 1 SGT, 3 Specialists.Elites only require 3 non-specialists per each Specialist.-PFC joe
Aim is not cumulative.You do not get +6 for spending two actions.It does carry over if you don't kill the target with the first hit though.The Sniper ability does not give you a +6 either.Aim does not confer extra damage either.Critical Hits (a natural one on a d20 roll) add 4 damage to the attack.-PFC joe
While the ratio is not bullet pointed, it is obvious if you compare elite units to grunt ones. That should end arguments. As for the cumulative AIM thing...Page 42, Section 6, Subsection.2.4, second paragraph, first sentence...AIM IS NOT CUMULATIVE.
An here I thought I was helping...oh well.
