What does refit/reserve status have on combat?

[vsek]

I noticed sometimes a unit I pull off front lines for refit will suddenly be on front lines in combat if a breakout happens. If I forget to change its status does it matter for its combat effictiveness? Same question for reserve status?

Refit just gives the unit priority for receiving men and equipment during the logistics phase.

Reserve status allows the unit a chance to participate in combat in hexes it is not adjacent to, provided it has no enemy unit next to it.

Do units normally participate in combat in hexes they are adjacent to?

I am talking about units in reserve mode; if there is an enemy unit next to them then they won't join a battle as a reserve unit.
