Hi !
Chewie goes in melee with an enemy unit.
1) Chewie goes in melee, the opponent does the unit's cohesion then Yoda is placed in base contact with Chewie if able.
Or
2) Chewie goes in melee, Yoda is placed in base contact with Chewie then my opponent does the unit's cohesion.
If Chewie has charge, is there any change in the correct sequence ?
