Doctrine or not?

[Tony M]

Found it! 

I have a book called "Soviet Tactical Doctrine in WWII [As Found in: Handbook on USSR Military Forces TM-30-340]". It says a Soviet rifle regiment generally attacked on a front 1,500 yards wide. A Soviet rifle company on a front of "up to 350 yards," and a Soviet platoon on a front of "up to 100 yards." 

A rifle company defended on a front 700 yards wide and 700 yards deep.

I have no idea how Romanian infantry units operated. My study of Axis allied armed forces is still in its infancy.
