The "Marines" unit type flag and the "AttFromNonNative" unit class flag has moved to the ruleset. They get meaning from action enablers. You can now control if/when "Attack" and "Conquer Unit" can be done with respect to tile nativity/livability. You also control their help text.
- Have your "act from non native" flags control all attacks, caravan actions and spy actions. (Change the help text from "Attack" to "act" or something like that)
- You can give a unit the ability to attack and conquer cities from a non native tile when its owner researches a special tech.
- You can give special act from non native tile ability to certain nations (think Vikings).
