Attack, raid, reinforce
The Rally Point send screen is four different games sharing one troop picker. The radio button matters more than the army.
Reinforcement
Troops arrive and stay. They defend. They eat the destination’s crop. The owner can send them home. This is how defence calling works. On this world you can also reinforce an unoccupied oasis.
Normal attack
Fight to the death. Survivors steal what they can carry. Rams and catapults fire. Chiefs can take the village if every conquest rule is met. Incoming attacks and raids trigger attack alerts.
Raid
Troops bounce after the fight. Buildings do not come down. Chiefs do not take the village. This is farming. Use it on crannies and oases.
Scout
Information only. Does not set off the attack-alert toast. See scouting.
