When to research
Patrol sends six Tercios for 150 Food and 150 Coin, making it a quick United States response to a ground threat. It can be researched again after a 160-second shared cooldown with Patrol, Levy and Conscription across the eligible buildings. Time the first use for a real defense or push, then track the shared cooldown before counting on another group.
Repeatable United States reinforcement
Patrol is a United States Commerce Age technology unlocked by the Spanish Immigrants Home City Card. It can be researched at Town Centers, Outposts, Blockhouses, and Forts for 150 Food and 150 Coin, and spawns six Tercios at the building used. It takes five seconds. The technology can be used repeatedly, but has a 160-second cooldown shared across buildings with Patrol, Levy, or Conscription.
Defend multiple approaches
Because several building types can call the reinforcement, Patrol can respond from the structure closest to a threatened area. The shared cooldown prevents using every Town Center or Fort as a separate simultaneous charge; plan around one use every 160 seconds across the network. Tercios can help repel Cavalry or add a quick defensive group, but the player must still pay the resource cost each time and make room for the units. Keep the relevant buildings safe and select the spawn point that places the troops where the next fight is likely to happen.
