Chénier, what do you think about the idea of having low-risk options have a much higher fail rate, but also much lower capture chance?
I think there should be easy "training" missions--such as "sneak into a farmhouse and murder the farmer and his family". Success does only minor damage to the enemy--he likely won't notice 5 dead peasants--but at the same time, the infil is probably going to get away with it.
