But what does an RS have when they run a BAR and a 1919?
Well you have to think the suggested design similar to VG and Obers in a smaller scale.
The 5 men unit that bleeds less is there to screen for the damage dealer that are LMG grenadiers.
The 5 men unit is more geared for attrition fighting while the lmg grenadier are more about dishing out damage.
As for riflemen equipped with BAR and 1919 the are good at all ranges. The reason why this was not that problematic was that the whole faction used to be based around riflemen so they where designed to be OP because the faction had an incomplete roster. Point here is that Grenadier should not be able to get both the g43 and LMG, if they can not stand up to BAR/M1919 riflemen it is the riflemen that need to change.
