Move and Shoot LMGs

I am very concerned about the proliferation of Shoot on the Scoot LMGs in EF. I do not yet have a working pipeline for Corsix, so please bear with my limited knowledge base. My initial concern is how does this function work?
1. Does Shoot on the Scoot work as a squad ability, a weapons characteristic or as an upgrade ability? Presently 3 of 5 Sov infantry types are eligible for the squad ability. Any squad that picks up a DP would have the ability if it is a weapons characteristic. Presumably any Soviet Squad that retrieves a DP would have the ability if it is an upgrade?
2. How does the accuracy and suppression of the LMG vary when used at rest or on the scoot? Burst length? Rate of Fire? Is the squad's speed reduced? Is there any difference? For comparison purposes only what are the similar differences in effectiveness of a WM MG34/42 on a bike, gren squad, MG squad, Pz IV?
3.Ostheer of course will provide similar capabilities for that faction since in keeping with EF's (appropriately so), non-political policy, Neither Ivan nor Fritz are uber-mensch?
4.Given that the Sovs and Ostheer will both have Shoot on the Scoot, how will this effect the balance for Vanilla Factions? As much as I might like to have Shoot on the Scoot ATHTs and mortar HTs, it ain't gonna happen in EF. Of course a shoot on the scoot Nashorn is a possibility?  ???

It's a weapon feature. Currently, Naval and Shock Guards DP-28 can do that, if the weapon is dropped and picked up by another squad, they should be able to fire it on the move.

Bike MG:
while moving:
acc. multi. -> 0.5
burst mult. -> 1
cooldown mult. -> 1

normal accuracy 0.25/0.25/0.4/0.55

Naval DP-28
while moving:
acc. multi. -> 0.5
burst mult. -> 1
cooldown mult. -> 1

normal accuracy 0.13/0.13/0.3/0.75

Don't know, maybe :-\.

I don't think so, we don't modify vanilla balance. About the nashorn, is intended to fire only when locked down.

Thank you. You have eliminated most of my concerns. If I understand correctly Strelky do not have the Shoot on the scoot ability. Do you know by any chance if NI has the ability to shoot on the scoot with its anti-tank rifle or is that a vanilla part of the weapons pack?

PTRD can't fire on the move. Strelky DPs do not either.
