When to research
Topçu Corps provides an immediate reinforcement: 3 Great Bombards; Great Bombard population cost -1. Research when this force fills a current army need and can reach the fight in time; reserve population and set a safe gather point rather than starting it as an emergency response. Use the Mosque for research. Research takes 15 seconds and costs 2,000 coin.
Great Bombard shipment and population relief
The Industrial Age Mosque research costs 2,000 Coin and takes 15 seconds. It delivers three Great Bombards and reduces Great Bombard population cost by one. Keep the guns protected by an infantry screen and reserve population for the shipment before starting the research. Its value is highest when the Ottoman army can use heavy artillery and the economy can afford the substantial Coin payment.
Three Great Bombards and a population discount
The Ottoman Industrial Age Mosque technology costs 2,000 Coin and takes 15 seconds. It delivers three Great Bombards and reduces Great Bombard population cost by one. That combines a large artillery arrival with a discount for the relevant unit line, but does not reduce the Bombards' resource cost or protect them from counter-artillery. Reserve population for the incoming guns before research completes and prepare an infantry screen so cavalry cannot reach the artillery freely.
Use the shipment to support a siege plan
Topçu Corps is most useful when the Ottoman army has a target that benefits from heavy artillery, such as a defended position that must be broken. The Great Bombards need time and protection to reach that target; do not send them unsupported into a mobile enemy force. Compare the Coin investment with the remaining army's need for anti-infantry units and screens. If the opponent can avoid the guns or attack the economy elsewhere, establish control of the route before committing the whole force to a slow siege.
