Military Reform-Improve Heavy Units

"With this decision, all Heavy infantry types available to your nation, if they have a possible upgrade, will be improved."

How do you know if your heavy infantry units have an upgrade? This would be an expensive waste of money to select of your nation does have any Heavy infantry than can be upgraded.

I *think* that its any regular HI only (this includes any factional tribal units), so excluded are Phalanx/Silver Shields and the various regional HI (such as the Galatians). Obv Rome has its own, unique, upgrade path.
