* '''Expedition(遠征)''' - Send your fleet to search for materials. They won't take damage or engage in fights, but there is an ammo/fuel cost and some expeditions can take quite a long time. Some expedition such as the support expedition available for world 5 onwards will cost bauxite.

After choosing to Sortie you'll be asked to choose a map, which your fleet will explore. Depending on the map, the path the fleet takes may be random or may depend on the ship types you have equipped; see the [http://kancolle.wikia.com/wiki/Sortie wiki pages] about the individual maps for details.

Ships will not sink as long they '''''are not'' heavily damaged (大破)'''. A non-heavily damaged ship (including minorly damaged小破/moderately damaged中破) will stay alive with 1HP even if she took excessive damage, and the rest of the damage taken will be shown as "Miss". '''If you continue the sortie(進撃)''' with a ship heavily damaged and entered a new battle''''', they are at risk of sinking''' and being lost forever!'''''<span style="font-size:14px;"> </span>'''<span style="font-size:14px;">The exception is your</span>'''<span style="font-size:14px;"> </span>'''flagship'''<span style="font-size:14px;"> (the first ship in your fleet), </span>'''<span style="font-size:14px;">which can</span>'''<span style="font-size:14px;"> never be sunk.

When you fight a battle you can choose a formation. The Japanese wikis contradict each other on the exact effects of these formations but here are general points of agreement.

Before you fight a battle you can choose a formation if you have 4 or more ships in your fleet.

* {{LineAhead}} '''Line ahead''' - Offensive formation that greatly increases all gun damage and decreases armor. Weak against aircraft, especially weak against submarines. Lowest chance of flagship protection.

* {{LineAhead}} '''Line ahead''' - Offensive formation that maximizes torpedo damage, torpedo accuracy and shelling damage.  Weak against submarines. Lowest chance of flagship protection.  Default formation for 3 or less ships.

* {{DoubleLine}} '''Double line''' - Balanced formation that slightly increases armor, evasion and all damage. Weak against submarines.

* {{DoubleLine}} '''Double line''' - Balanced formation that gives the highest accuracy in shelling, but less damage than line ahead.  Torpedoes have moderate accuracy and damage.  Moderately weak against submarines.  Available at 4 ships.

* {{Diamond}} '''Diamond''' - Defensive formation that greatly decreases gun damage while increasing accuracy. Strong against submarines, very strong against aircraft. This formation also increase the chance that other ships will take damage instead of your flagship (flagship protection).

* {{Diamond}} '''Diamond''' - Anti-air formation that decreases accuracy and shelling damage. Strong against submarines, and very strong against aircraft.  Very bad for torpedoes.  This formation also increases the chance that other ships will take damage instead of your flagship (flagship protection).  Available at 5 ships.

* {{Echelon}} '''Echelon''' - This formation is the least well tested but it is thought to be a balanced defensive formation which is strong against submarines.

* {{Echelon}} '''Echelon''' - This formation is the least well-tested, but it is thought to be a defensive formation.  Somewhat strong against submarines.  Bad for torpedoes and surface combat.  Available at 4 ships.

* {{LineAbreast}} '''Line abreast''' - Defensive formation that greatly decreases all your gun damage and increases accuracy, armor and evasion. Very strong against submarines.

* {{LineAbreast}} '''Line abreast''' - The best anti-submarine formation, but greatly decreases shelling damage.  Very bad for torpedoes.  Available at 4 ships.

When your fleet uses heavy ships and carriers it is recommended you choose a damage-boosting formation, while if your fleet uses light ships with torpedos and does most of its damage during the night you should choose a defensive formation. If you're unsure, double line is almost always a good choice.

Unless you are fighting submarines, line ahead and double line are almost always good choices.  Fleets heavily reliant on torpedoes for damage should choose line ahead.

If you do not wipe out the enemy fleet during the day, after the first stage of the battle you will have the option to make a '''night attack (夜戦突入)''' . The damage of both your own ships and those of the enemy is greatly increased during a night attack; also, ships can fire torpedos at night, which are generally far deadlier than those guns equippable on destroyers and light cruisers. Select '''stop pursuit(追撃せず) '''if you wish to end the battle'''.'''

After the battle, the battle result will be shown. You will receive a [http://kancolle.wikia.com/wiki/Combat#Victory_Conditions battle rank] largely dependent on how badly you damaged the enemy fleet (the highest rank, 完全勝利 requires you to completely destroy all enemies while taking no damage.) You may have a chance to obtain a new ship girl at this time. The rarity of the ship girl you can obtain depends on the battle rank.

If the battle was not a dead end on the map, you will be given the option to '''advance(進撃)''', or '''retreat(撤退)''' to end the sortie. To unlock the next zone, you will need to obtain a victory against the boss fleet (the larger, horned red dot on the map.)
