Shinkichon
Rocket Carts and Turtle Ships gain range and fire additional rockets.

Overview
Rocket Carts and Turtle Ships gain range and fire additional rockets.
Effect and affected units
Shinkichon changes rocket Cart: +1 range, +6 projectiles; Turtle Ship: +1 range, +2 projectiles (rocket attack). Read the named target carefully: this effect applies only to the units, buildings, or economy described in its entry. This is the main reason to research it; compare the affected units with the army you expect to field.
Research cost and timing
Research is available in Imperial Age at the Castle. The recorded cost is not separately recorded, and the research time is 60 seconds. Consider whether the upgrade will affect enough units or workers to repay that investment before the match is decided.
Matchup plan: Shinkichon Rocket Cart transition
Shinkichon changes the value of the Korean siege line by strengthening Rocket Carts, making it a key decision when choosing between siege upgrades and heavier cart production. Compare the technology’s volley value with the extra durability and blast radius of the elite upgrade When Rocket Carts are already part of the army, research Shinkichon before expanding that line if its damage increase will help break the current unit mass or defenses. Keep the carts behind a screen and use their volleys against clustered targets or structures while faster units spot and protect them. Add the Heavy Rocket Cart upgrade when the extra armor and area effect are more useful than another immediate damage improvement The carts are still vulnerable if the screen collapses, and their slow movement makes repositioning costly. Do not research the upgrade when you do not plan to field Rocket Carts or when resources are needed to complete the army’s core counters
Effect and research timing
Rocket Carts and Turtle Ships gain range and fire additional rockets. Effect: Rocket Cart: +1 range, +6 projectiles; Turtle Ship: +1 range, +2 projectiles (rocket attack). Research becomes available in: Imperial Age; Research at: Castle; Research time: 60 seconds. This research is restricted to its named civilization, so it is part of that faction’s identity rather than a shared option. Its value depends on which units receive the effect and how often they take part in combat; timing it before a major engagement can improve the whole eligible group.
