Types of Map Nodes
Note: All consumption amounts listed are rounded down, to a minimum of at least 1 Fuel/Ammo consumed.

Day Battle Node
Main Article: Combat/Day Combat

A day battle node

Day Battle nodes are the standard type of battle nodes encountered during sorties, and are marked with a red circle on the map. Both fleets will engage in three main phases of combat in order, namely Aerial Phase, Shelling Phase and Torpedo Phase. Depending on the type of fleet used, or the type of enemy fleet fought (ie. Combat/Combined Fleet), the order of Shelling and Torpedo Phase might be altered.

After initial combat ends, the player is given an option to extend the battle into the Night Phase at the expense of additional ammo and morale.

Day Battle Nodes consume 20% Fuel and Ammo. If the battle continues into the night, the ammo cost is instead 30%.

Night Battle Node
Main Article: Combat/Night Battle A night battle node  A night-to-day battle node Night Battle nodes are marked in purple on the map. Night Battle nodes differ in that the battle starts immediately under night conditions, and ends the battle immediately upon completion.

Events may feature nodes marked as night-to-day battle nodes, which involve a night battle where your fleet fights an enemy combined fleet, followed by a day battle against the enemy main fleet. Proceeding from night to day only occurs when certain requirements are met. When they are met, the transition happens automatically - unlike going from day to night battle, you do not have any control over whether this happens.

As of the Fall 2017 Event, Night Battle Nodes now consume 10% Fuel and 10% Ammo.

This behavior was extended to regular world maps with the Phase 2 [Block-1] Update.

Aerial Battle Node
An aerial battle node Introduced in Summer 2014 Event, Aerial Battle Nodes differ in that the battle instead consists of two separate Aerial Phases. Plane counts are affected per phase, and anti-air mechanics apply for both phases.

Like normal Day Battle nodes, the player is given an option to extend the battle into the Night Phase.

Aerial Battle Nodes consume 4% Fuel and 8% Ammo. If the battle continues into the night, the ammo cost is instead 12%.

Air Raid Node
An air raid node

Also known as: Air Raid Battle (空襲戦)

First introduced in Winter 2016 Event.

Unlike Aerial Battle nodes, Air Raid Battle nodes are defensive battles where the victory objective is to minimize, or outright neutralize damage dealt to your ships.

There are a few key differences with an Air Raid Battle versus regular battles:
 * The battle consists of a single aerial phase, in which allied bombers are unable to attack the enemy fleet.
 * Abyssal aircraft will attempt to bomb your fleet. Your fleet will launch any aircraft capable of participating in the Aerial Combat phase to intercept them.
 * As it is an air-raid node, it is advised to use diamond (for single fleet/striking force) or ring (for combined fleet) formation for the battle.
 * The only means of directly damaging the enemy fleet is through the use of bombers sent to the node via Land Base Aerial Support. Damage dealt to the enemy fleet is not considered for determining battle victory ranks.
 * These nodes calculate ranks solely based on the damage you take during the air raid:
 * Perfect S: Take zero damage from the air raid. Annihilation of enemy bombers is optional.
 * A: Take less than 10% damage
 * B: Take 10%-20% damage
 * C: Take 20%-50% damage
 * Air Raid nodes cannot be extended into Night Battle.

As of the Fall 2017 Event, Air Raid nodes consume 6% Fuel and 4% Ammo.

This behavior was extended to regular world maps with the Phase 2 [Block-1] Update.

Submarine Node
As of the Fall 2017 Event, nodes containing only submarines consume 8% fuel (rounded down, but 1 unit at minimum). The consumption is unchanged regardless of starting in day or nighttime.

This behavior was extended to regular world maps with the Phase 2 [Block-1] Update.

PT Imp Node
As of the Fall 2017 Event, nodes containing only PT Imp Packs consume 4% Fuel and 8% Ammo (rounded down, but 1 unit at minimum). The consumption is unchanged regardless of starting in day or nighttime.

If continuing a PT Imp Node from day to night, the ammo cost is instead 12% Ammo

Ambush Node
An ambush node

Introduced in Winter 2019 Event, Ambush nodes are nodes where battle occurs with an abyssal enemy fleet, but the player fleet is unable to attack. Although the displayed background is nighttime, the battle will follow day battle rules, wherein the enemy fleet is granted air superiority and will proc artillery spotting accordingly. The battle will also adhere to the daytime damage cap.

Ambush nodes automatically select the formation and starts the battle immediately for the player once the fleet arrives on the node. (Line Ahead for Single Fleet, Formation 4 for Combined, or Formation 2 if not possible) Ships can be sunk in this node as per normal sinking rules (Continuing sortie while below <25% HP) so closing the game, or refreshing has to be done before the ship reaches the ambush node in question.

Ambush nodes consume 4% Fuel and 0% Ammo.

Node Selection
Also known as Manual Node Selection

Introduced in Spring 2015 Event, certain nodes allow you click on a node to specify which route you want to take. You may only choose nodes that are connected directly to the node you are currently at.

Multiple Starting Points
Introduced in Winter 2016 Event, maps with multiple starting points were introduced. These maps may have multiple starting or/and ending nodes. The starting node your fleet begins at depends on the fleet type, or composition of the fleet depending on the map.

For example, in this image, there were multiple start and end nodes in E3 of the Winter 2016 Event. The type of combined fleet used in this map influenced which starting node the fleet began at. Different phases of the map could only be completed by starting at a different point.
