This directly from the manual
The Romanian Front (both Axis and Soviet units in this area) is frozen on turns 1 and 2. Axis and Soviet ground units in this area can’t move, air units may move and fly missions. During a Soviet Logistics phase, if Axis forces control any hex that is both east of hex column 51 and in a hex row between 89 and 94 (all inclusive), then these forces will unfreeze.
I have met the criterea for this and as I understand the above rule all units south of hex row 94 (& this includes those units that are attached to the SW Front) should be frozen on the first & second turns so long as there are no Axis forces or ZoC in the above hexes. I did a test and found that not only were the SW Fronts units (5th Army?) on the Romanian border active on the Soviet first turn but so to were elements from the Southern Front as well.
Now you could argue that as the SW Front had been attacked in the North that all of its attached Army's / Units should be released, but I believe that, that particular argument would be specious at best, as those units would have been placed there to stop / slow any Axis incursion from Romania
I know that most peoples 1st Turn includes the super Lvov pocket but if this was corrected (assuming that it is an error) it allows for a more historical style of gameplay
