=Historical Background=
<!--<div class="mw-collapsible mw-collapsed">-->

==Operation Tatsumaki==
''Copied from [https://codenames.info/operation/tatsumaki/ here]:

Tatsumaki was the Japanese submarine component of the "Yu" plan (Yu-Go) to decimate the US Fast Carrier Task Force in the lagoon of Majuro atoll in the Marshall islands group (May 1944).
*It involved the use of a 5 submarines attack force to deliver the main blow to the US stationary forces.
**Each submarine would carry two "''Type 4 Ka-Tsu amphibious landing craft''", with each craft specially modified to carry 2 torpedoes.
*One additional submarine was used for reconnaissance 
*7 more submarines were positioned to intercept any potential fleeing target.
*The submarine force was supported by one submarine tender.
This would have been like a "Second Pearl Harbor Attack", a surprise attack supposed to deal a decisive blow to the American Navy.

*''More information on the "Yu" plan [http://www.combinedfleet.com/U-GO.htm here]

===New Mechanics===
*Uniquely on '''"atoll nodes"''', it is possibly to deploy the new {{Amphibious Tank}} {{Equipment/Link|Special Type 4 Amphibious Tank|text=Ka-Tsu}} and {{Equipment/Link|Special Type 4 Amphibious Tank Kai|text=Ka-Tsu Kai}}
**''On those nodes, regular [[oTorp]] will not work,
**This can only be deployed by SS, SSV, and the AV [[Mikuma Kai Ni Toku]], [[Nisshin A]], and [[Mizuho Kai]] fast,
**They must carry at least one Ka-Tsu tank,
**On the "atoll node", ships meeting those requirements will carry out a special opening torpedo attack,
**In night battle, those ships will additionally trigger the same attack as a cutin,
**Using several Ka-Tsu tanks on a same ship will make it carry out several of those attacks in a row (day and night),
***This attack utilizes a new special animation, with the tank climbing the atoll's soil.
