It’s a pain having to unequip a soldier sent to reserve (before or after), then equip his replacement.
Can there be a single button swap please? Highlight 2 soldiers - press button to swap places, system swaps all equipment that is appropriate, leave anything that isn’t or send it to the weapon/equipment pool - either would be OK I think. Eg a radio would stay with a radio-man, an ATR couldn’t be changed to equip an assaulter so would go to the pool, med kits, grenades, sidearms, second weapon all swap up to the limit of places the new soldier has, remainders go to pool, etc.
