Each unit type's activation card grants its models one or two actions, so unit quality sets the action count.
How it works
Cards are drawn in turn; when a card for a unit type comes up, all models of that type activate and take one (or two) actions as printed on the card. Samurai cards and one Ronin card give 2 actions, while Ninja, Ashigaru, Civilian and the other Ronin cards give 1. A Banzai bonus card gives extra activation to Ninja and heroes. An action is move up to 6" (Ninja sprint 9"), move into melee, shoot, or another action such as opening a chest.
all the units or models of that type are activated and may take one (or two) actions, depending on the card. There are the following cards: 4 Ninja cards with 1 Action ... 2 Samurai cards with 2 Actions
