Well the Semi-Automatic Rifle profile came first.
I'd have thought that the OST sniper G43 came first.
Though honestly it's immaterial, Even "only" a four times scope is not a logical choice for a CQB weapon, and given that it is a scoped rifle, it really makes more sense for them to be long-ranged weapons.
STGs exist to be the "cqb" option for Axis squads, if that's something people want.
