Q: I have Garen, Commander at a battlefield along with a Recruit token. Thanks to Garen, the Recruit has 2 Might. My opponent's total Might during the combat damage step is 6, so they deal 5 damage to Garen and 1 to the Recruit. Does the Recruit die?
No. Under the revised rules, combat damage is dealt, any units with lethal damage on them are killed, and then units are immediately healed of all damage before lethal damage is checked again.
This means that if one of your units that died was providing a Might boost to other units, they're healed of any damage before losing that Might boost. This is a change from previous rulings that impacts cards including Captain Farron; Taric, Protector; Garen, Commander; and Darius, Executioner.
