The discussion concerned how it is wise for the Soviet player to set his artillery TOEs to 50% so that all armament points are used making rifles (that then put soldiers into squads) rather than guns, because in all the retreating you do in 1941, you lose a ton of guns (why build them when you just lose them when you retreat?).
So there are a lot of good SU types to reduce at various times in the game, and rather than do 1 at a time, you can use the commander's report to manage all of this much more easily (though not necessarily in "one fell swoop" so forgive the thread title).
Give me a minute to put the screenshots into this space, and I'll update it:
