If escort efficiency falls below 100%, some or all of the defending ships will arrive late to the battle when friendly convoys are attacked, increasing the likelihood of convoys being destroyed by the attackers. When escort efficiency is 100% among task forces within a given fleet, one of these task forces will instantly come to the defence of any convoys under attack within the fleet's assigned regions. However, when troop transfers are being performed automatically as part of a naval invasion order, the naval invasion support mission may be a more appropriate choice.Д®scort efficiency is an important metric in relation to convoy escort missions. It is worth noting that troop transfers across water are performed using convoys, and can be protected through this mission like any other convoy. This can be useful for determining which strategic regions require convoy escort coverage. When the strategic navy map mode is selected, existing convoy routes are shown on the map. Along with other important information, this maximum number of regions is visible when the cursor is hovered over the convoy escort mission icon in the centre of any region where the mission is taking place.

This protection is extended to all of the fleet's assigned regions, although the number of regions that can be efficiently protected depends upon the number and size of task forces performing the mission within a given fleet. If you spot a mistake then you are welcome to fix it.ДЄ task force assigned to the convoy escort mission will protect convoys belonging to the player or their allies if they are attacked. If a fleet does not have enough raiding task forces for the area it covers, their efficiency will be reduced. The raiding force needs to spot the convoys before attacking them.Д®ach raiding task force can only efficiently cover 1.5 strategic regions. This mission assigns a task force to look for enemy convoys in the fleet's operational area. In addition to its main task of intercepting and engaging enemy forces, a strike force can passively project naval supremacy across its fleet's assigned regions, provided that these regions are within range of the strike force. if the enemy force appears too strong for the strike force to safely handle.ДЄlthough a strike force can be assigned to cover a wide area, it may not arrive in time to engage the enemy if the spotted enemy force is far from the strike force's port. When a strike force has left port to intercept an enemy force, the player can still manually order the strike force to stop intercepting and return to port, e.g. An engagement rule of 'Never engage' would cause a strike force to remain in port indefinitely, while an engagement rule of 'Always engage' would allow a strike force to intercept and engage an enemy force regardless of its strength. When not intercepting enemy forces, a strike force will remain in port to conserve fuel.ДЄ strike force will only choose to intercept and engage a spotted enemy force if their engagement rule permits it. The strike force does not need to be in the same fleet as the patrolling task force in order for this coordination to occur. If the patrolling task force is set to 'Never engage', it will avoid battle until the summoned strike force arrives, and it will begin disengaging immediately after the battle starts.ДЄ task force assigned to the strike force mission can automatically intercept and engage enemy forces within their fleet's assigned regions, after an enemy force has been fully spotted by a patrolling task force belonging to the same country. Any strike forces assigned to the region (regardless of their parent fleet) may also choose to leave port and engage the enemy, depending upon their own engagement rules.

A patrol can only spot one enemy task force at a time and vice versa.Д®ngaging the enemy ДЄfter an enemy force is fully spotted, the patrolling task force may choose to engage the enemy immediately, depending upon their assigned engagement rule. The patrol can only start spotting enemy submarine forces with a probability of each hour. If the hourly change would be zero or negative, the task force can't spot that enemy. The spotting progress starts at base spotting chance and increases by hourly change until it reaches 100%. When the enemy force is 100% spotted, it becomes possible to engage them in battle.

This process is called spotting, and its progress is measured as a percentage which is visible in a tooltip. When enemy ship(s) have been found, the patrolling task force will gradually gather information about the enemy force.

A single task force can only patrol a single strategic region at once, so multiple task forces are required to patrol multiple regions.
