Introduction
日本海軍が開発、「竜巻作戦」で魚雷や火器を装備して環礁泊地の航空母艦を奇襲攻撃しようと準備した水陸両用戦闘車両、「特四式内火艇」、通称カツ車です。
元々は揚陸用水陸両用輸送車両として開発されました。
実際には機動性や騒音などに致命的な問題があり、作戦は中止されています。
作戦部隊の意見具申により大きく改修されたif改修型、ぜひ幻の運用を！
This is an amphibious combat vehicle developed by the Japanese Navy during "Operation Tatsumaki", equipped with torpedoes and guns, and prepared to attack aircraft carriers anchored in atolls, the "Special Type 4 Amphibious Tank", commonly known as Ka-Tsu.
It was originally developed as an amphibious transport vehicle.
In reality, there were fatal flaws with mobility and noise, and the operation was canceled.
This "what if" variant has been greatly improved based on the feedback of the operational team, so please make good use of the surprise attack!
Mechanics
Special Type 4 Amphibious Tank is an 
Amphibious Vehicle:
- It greatly increases expedition resources gain.
- It greatly increases Resource Nodes resources gain.
- It slightly increases TP gauge drain during Transport Operations.
- It deals adequate damage against installations, being a good component for "nukes" (see Anti-Installation).
- It also allows Submarines to participate in the shelling phase against Installations, by launching the tank in battle.
- It has an extra bonus against PT boats.

Uniquely on "Atoll Nodes", it is possible to deploy the Ka-Tsu tanks
to trigger a special Opening Torpedo Salvo.
- 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,
- This attack overrides regular Night Cut-ins attacks (e.g. if a ship is setuped for a TCI, it will still trigger the Ka-Tsu attack).
- Using several Ka-Tsu tanks on a same ship will make it carry out several of those attacks in a row (day and night),
- It capped at 2 attacks per ship at night.
- This attack utilizes a new special animation, with the tank climbing the atoll's soil.
Can be equipped in the RE of I-36, I-41, I-47 Kai, and I-58 Kai.
Notes
This equipment is often referred to by its official Japanese name "Ka-Tsu".
Not to be confused with other "Landing Equipment/Tanks" (see here).
