Farsighted Iden

Units cannot move through a ground vehicle. However, what happens if the base of a ground vehicle is at an angle due to terrain (of less than 45degrees to the table surface) such that it creates a physical gap underneath the model's base that is large enough for the movement tool to be placed flat on the table in line with the rules for movement? Could a unit (not on a notched base) perform a move "under" the vehicle? Follow on question: a model's base cannot be placed overlapping another model's base. What does this mean specifically? Do the two bases need to be physically touching each other (i.e. on top of), or does it count as overlapping if the base of one model is not touching another, but when viewed from top down on a 2D plane the lower base is partially obscured by the higher base (i.e. above)? If the latter, does terrain override this - such as a bridge or ledge? Thanks.

If during a ranged attack (using a Non-Suppressive weapon), an attacking unit rolls their attack dice and gets a hit result, then subsequently re-rolls that die and their final attack pool result has no hits and no criticals in it does the attack allocate Suppression to the defending unit? The wording is ambiguous as the Assign Suppression Token to Defender section states that if there were any Hit or Critical results in the attack pool during the Roll Attack Dice step then suppression is allocated. It could be interpreted that there was a hit in the attack pool during the Roll Attack Dice step (prior to the re-roll), even though the end result after re-rolls didn't have any hit results.
