I'm the other white meat.
The return of Privateer is a very good news, but why not extending the concept of hidden nationality to land units?.
I mostly play in multiplayer games, and people are often reluctant to attack other players; they are afraid of starting a never ending war.
With hidden nationality land units, it becomes possible to damage opponent's land, cities and units without entering a total war.
By hidden nationality land units, I think about rebels, mercenaries, terrorists. These units would be quiet expensive, and only foot units (I mean no tanks, no planes), to avoid people doing war with army of hidden nationality units.
Specific technologies / buildings would be necessary to build them.
I understand Firaxis may be reluctant to introduce terrorism related concept in Civilization, because of 9/11 and Iraq, but this is part of human civilization (Terrorism is not an invention of the 20th century), it shaped our world.
What do you think?
Probably one of the many "sounds great in theory but when playtested turns out to be exploitable or simply UN-FUN".
I'm seeing the uselessness of Open Borders agreements, the frustration of the human player as the AI's send wave after wave of 'neutral' units - especially on higher difficulties with their inherent 'build' bonuses - and increased micromanagement of units to defend against, what is essentially, modern barbarians.
If this was introduced, it would be nice if these neutral units or guerrillas carried a substantially higher upkeep cost to represent the bureaucracy needed to create shell corporations & supply lines to establish untraceable methods of funding. Also, to pay enough to a solitary unit to essentially single-handedly attack a nation!!

I think it would be interesting if they are defeated in enemy territory and there was a percentage chance of them revealing where their funding comes from, creating an instant war or -at a minimum- a massive negative modifier to relations.
In multi-player, I am sure we would see a lot of 'Highest Scoring Player' getting dogpiled by vast numbers of 'hidden nationality' fighters as the weaker players (in that specific game) band together and invade en masse. Would probably get frustrating fast.

Maybe there is balanced solution.
