So as not to open a new topic, I'll post something I found about captured vehicles in Soviet service.
Source is: M. Kolomiets & I. Moschansky,
Trofei v Krasnoy Armii, Frontovaya Illjustratsiya No 1, 2000.
SU-150 - this is a German
Hummel
SU-88 - this is a German
Nashorn
Both were available since
3/45.
These captured vehicles were actually formed into platoons and used on the front lines, so there are grounds for adding them - if there's space in the Soviet OOB of course.
There was also a single captured German
Wespe (designated SU-105) since 4/45, but since it's a one-of-a-kind it can probably be omitted.
It also lists the following captured
Hungarian vehicles, all available from 9/44: Turan, Toldi, Zrinyi, Nimrod
The big problem is, there are
no details on which model of said vehicles were used, or their designation in Soviet service, so I guess there's probably no point in adding them unless someone can find out this additional information.
A summary table can be found here:
