I guess it would be better to represent this by adding support to the game for guns produced like tanks. That way you could model LL delivery exactly.
What fundamental difference is there between artillery ground elements and tank ground elements?
I am somewhat confused, because I would have assumed these to be basically the same, just with other values for the devices and such.
That was a concern over LL assets and how the game handles them, ( LL cant be interdicted in game afaict, and the SU just gets numbers of x y or z assets delivered over time, compared to the production phase which can be influenced in game and reduce SU production levels) SU sources list LL as SU produced in SU for many instances, so there is often a difference between what the W Allies sent, and arrived, and what the SU produced etc, roughly a third of smaller AT guns originated from Uk/USA but this is often lost in the numbers game and included in the SU production numbers.
Im unsure of how the game models this but suspect the LL deliveries just add to production totals, ie outside of the production phase, and morvael concern is how to better model it.
