The Tank Center improves Tank Heroes through HP, ATK, DEF and Squad Size bonuses. Construction requires Base level 14.
Squad size and hero stats
Tank Hero Squad Size is a unit-capacity stat. It is separate from the number of squads you can send onto the map. Another Squad building supplies an additional march slot; the Tank Center supports the Tank Heroes within formations.
At level 20, the center adds 67 Squad Size, 12,750 HP, 496 ATK and 100 DEF. At level 30, those values become 100 Squad Size, 25,500 HP, 744 ATK and 150 DEF.
Wall of Honor and research
Level 20 also unlocks the Wall of Honor for Tank Heroes. Tank research includes its own Squad Size improvements, separate from the center's building-level bonuses.
The Infantry Center and Aircraft Center affect their respective types. In a mixed lineup, each hero's type determines which center's type-specific bonuses are relevant. Building power is a different number from the stats shown for a hero or a deployed squad.
