Syntax:
   UNLOAD [weapon]      Removes ammunition from a ranged weapon.

With one hand free, the ammunition is moved to that hand. This means ammunition from a weapon in the right hand normally goes to the left hand, while ammunition from a weapon in the left hand goes to the right hand.
If both hands are occupied, the ammunition falls to the ground.
Unloading stops any aim in progress first.
Unloading while hidden or invisible involves a stealth contest against observers in the room. Visible observers who notice the action can be identified in the messaging. A creature that notices instead produces <Creature> notices your attempt to unload your <weapon> while remaining hidden!
Some ranged weapons use specialized unloading mechanics or messaging. For example, UNLOAD removes only the readied bolt from a repeating crossbow, leaving other bolts in its chamber.

You don't have a ranged weapon to unload. — the bare command found no weapon in your right hand.
You must be holding the weapon to do that. — the named weapon is not in either hand.
You can't unload such a weapon. — the named held item is not a ranged weapon or cannot use the standard unloading action.
But your <weapon> isn't loaded! — the weapon has no readied ammunition.
