Looking at the movement rules for space/vehicle combat...
As worded, no ship ever crosses from extreme to long, and only starfighters change from medium to long.
Speed 1 ships can only move between close and short.
Speed 2-4 can only move between Close, Short and Medium.
Speed 5+ can move between Close, Short, Medium, and Long.
(p 165)
This means two speed 1 ships can not get out of each other's range...
It really should be allowed to move between the longer ranges, just as can be done in personal. I don't care if it's 2 or 3 (or even 4) maneuvers per shift, but sometimes, you need to play out the approach battle... Especially if there's an interdictor involved.
For example, B-Wings and Y wings are speed 4... and assaulting an Imperial SD, the battle should begin at long range (as the ISD has Long ranged weapons), but if it does, neither can close, and the battle is over with all the fighters dead, because they cannot close.
Likewise, two ISD's facing each other can't get out of range. One's gonna die.
Also, the range band issue is more of a problem given the groups can start with multiple ships...
Note: This is a carried over flaw from the EOTE rules.
