You've just charged into the market square, eager to show the townsfolk that you're not afraid of the bridge troll there, and that they can count on you when needed. However, the bridge troll seems keen on keeping its career change to market troll, and its oversized forearms and blood-tipped claws are poised to neatly toss you aside once you are close enough.
You roll your attack and damage dice. The bridge troll gets a protection die to reduce your damage, due to its warty, matted hide, even if it doesn't use an action to defend. The rules allow the troll to choose to roll its die or take half of the max protection roll . . . but they don't explicitly require the attacker or defender to declare first.
Which sequence would you prefer?
Note: the default is for attacker to choose roll or half damage first, because defender rolls protection as a reaction to an attack. This allows the defender to choose taking half any time it would reduce the damage to the minimum amount, and choose rolling otherwise. The effect of this is to reduce the average amount of damage dealt (benefitting the defender) because the situations in which a low damage roll would have been met by a lower protection roll are minimized by the defender's option to take half protection after seeing the damage roll.
