Units

Combined arms - how units fit together

NationFall has four arms: land, air, naval, and missiles. Each has its own internal logic - what units exist, how they trade off, where they shine. The campaigns that win combine them.

You can win wars with one arm if your opponent neglects the others. You usually can't if they don't.

The four arms

Each links to a deeper page on what's available, how it progresses with era, and what doctrines win.

Why combined arms wins

Each arm has at least one fatal weakness. Land forces are slow without air cover and can be cut off without naval supply. Air forces can't hold ground. Navies can't reach inland targets. Missiles consume magazines no economy produces fast enough.

A campaign built around one arm hits its weakness and stalls. A campaign that integrates all four creates dilemmas the enemy cannot solve simultaneously. Air superiority over the front frees armor to maneuver; naval blockade strangles enemy magazine production; missile strikes degrade the AD network that was protecting the airspace your bombers need to operate in.

This is also why the multi-doctrine strike planner matters - splitting your air force across strike, SEAD, strategic, and counterforce roles is exactly the kind of integration that turns one-arm dominance into combined-arms pressure.

Era changes everything

Each arm exists in both scenarios - but with very different rosters.
