YouTuber Martin Fencka finds the correct sequencing of attacks to get the best value. His ranged naval forces of frigates and sole melee land unit in the area (his tercio) are attacking a Spanish city garrisoned by a ship and tercio. This game, Martin has the Honor policy tree, which among other bonuses grants his units +15 hit points when they kill an enemy unit with a melee attack. When a melee unit attacks, it both deals and receives damage, which can be dangerous. By first attacking the city with his ranged ships, he damaged the garrisoning enemy tercio without quite destroying it. This created a window to melee city with his own tercio, causing some damage to the city itself and successfully destroying the enemy unit. Martin’s tercio healed 15 hp by getting the kill, refunding most of the damage it sustained during the attack.
