Warlord
In my mod, I assigned Geurilla with hidden nationality, and it proved to be a huge hit perferred by both the AI and me 
In my game, the AI goes fanatical and sends waves of cavalry towards my barbaric army, and I doubt that my army would survive, so I wanted to move some defensively better units on to my pile so that the AI will not touch my army. Unfortunately, all I had were some warriors and swordsmen, so I ended the turn hoping that my geurillas will endure the attack.
Then the turn ended with the AI retreating all its troops... and my stack of barbarians wasn't confonted in any way, then I discovered that even a defensively weaker unit, which in my case, was a warrior, could "convince" the ai that attacking would be a declaration of war.
How about defending a city with a geurilla, would the ai attack? And if it would, would it capture the city? What if a warrior is also there, would the ai cease attacking? or would it just kill the geurilla and leave the warrior alone?

Ain't that a relief! No need for massive amount of troops to quell them and defend against culture flips.
