Finally each faction seems to be better oriented to fight a specific ranges and the soviets seem to have units for all ranges thus I see little point in it.
That's where doctrines get the job done.
I'm not saying.that all factions should have nondoc similar tools, but that the "rules" for equipment should be somewhat standardized.
Ab eventual STV long range weapon equivalent to g43 could be made doctrinal upgrade or standard issue for doctrinal units, and URRS retair their close range nondoc roster with the proper weapon classes (penals could be a 6 men mosin with 2 atv-40, cons remain the mid-close range low accuracy mosin unit).
STV could become guards standard weapon modified to be more long range oriented.
IF coh 2 teaches something, is that you should plan ahead such thing as weapon classes to give some kind of concistency.
Otherwise we end up with semi auto rifles that for some reasons abide to completely different rules and 3-4 version of G43, mp40, bren,...
