Well maybe there is an isolated case where 1 or 2 French elements are still being used. I am pretty certain the bulk of French elements/OBs aren't.
Regarding element '3010' (from above). I don't see it being used in the GC at least.
This is how you can know for sure....
1. Launch game editor.
2. Load scenario and/or generic data. (depending on the case)
3. Go to the CSV tab and export the the unit data.
4. From Windows, go to "\Gary Grigsby's War in the East 2\Dat\CSV" folder and open "xxxxx_unit.csv" in your favorite spreadsheet app. (you can use a text editor, but that would be painful in this case...)
5. If you go to the first row, you will see all the column headers, the columns you are interested in are (Sqd.u0, Sqd.u1, ... Sqd.u31)

These are the columns where Ground Element '3010' for the H-35 Light Tank would be listed if it is being used.
In the image attached, we just happen to be looking at the row data for the German 1st Infantry Division.

From that view, you can tell that it is using WIDs of ( 81, 84, 88, 427, 79, 91, 76, 77, 74, 75, 67, 68, 54, 110, 112, 1490 )
Those would be assigned to (Sqd.u0, Sqd.u1, Sqd.u2 ... Sqd.u15) with the remaining Sqd.u entries set to '0'.
So, you can see how, in this example, where Sqd.u0 & Sqd.u1 got its values.
Regarding the '3010', you can search the spread sheet and see if it shows up in any of the Sqd.u columns. If it doesn't, then it is not being used.
