Does recalling a unit exhaust it?

Ruling: Recalls do not inherently exhaust units. A unit only exhausts if the specific effect text says to exhaust it.

Nuances:

• A recall only happens when an effect specifically uses the word "recall" - moving units back to your base is not automatically a recall
• Many recall effects do say to recall the unit exhausted, but that's part of the effect text, not an inherent property of recalls
• Some cards have errata that affect recall effects, so check for updated card text rather than relying on printed text
