Why Development comes first
Development is the speed branch. Fast Builder, Research Enhancement, Focused Training and Rapid Field Dressing shorten the timers you deal with every day, while Hospital and Barracks Expansion raise capacity. Research that makes future research faster is the reason many players keep this branch moving from their first Tech Center levels onward.

It has 29 research and 141 levels, and it is available from Tech Center level 1, with its last requirements reaching level 26.
At base speed the full branch takes about 455 days and roughly 440 million Food, 440 million Iron and 1.32 billion Coins. Survival Skills is the longest single research at about 64 days, followed by Drill Grounds Expansion at about 50 days.
