In a crash site one of my soldiers was shot unconscious (took a nap on the field, in the end of mission survived with 1 hp and 21 days in sickbay).
After the mission I flew straight to a new crash site, didn't go to base, and the guy was at full hp. He didn't get wounded in the second mission and at base he was fine as well (full hp, 0 days in sickbay).
Also, everyone had all equipment restored for the second mission. (not sure if this one is supposed to be a feature.)
Sorry, don't have a save file for this one.
