Kommt ja immer drauf an wo die feindliche Unit steht. Aber ganz pauschal ist es so:
Quelle GW Rulebook Gratis pdf:
When a Reinforcement Unit is set up on the battlefield, that unit typically must be set up so that it is more than a specified distance away from any enemy models (e.g. ‘you can set up this unit anywhere on the battlefield that is more than 9" away from any enemy models). Whenever such a distance is specified when setting up a Reinforcement unit on the battlefield, that distance always applies to the horizontal distance, even though normally you measure to and from the closest part of a model’s base (or hull). That means, if we were to use the above example, when that unit is set up on the battlefield it must be set up more than 9" horizontally from any enemy models.
