Introduction

??

??

Mechanics

Amphibious Vehicles behave similarly to Landing Craft. They:

• Deal great damage to installation, being an essential component of the "nuke" (see Anti-Installation).
• Increase expedition resources gain.
• Greatly increase Resource Nodes resources gain.
• Slightly increase TP gauge drain during Transport Operations.
• Allow Submarines to participate in the shelling phase against Installations, by launching the tank in battle.

Can be equipped in the RE of I-36, 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).
