From gaming experience it has been my observation that Surprise is a rare event (in HoI2 version 1.2), probably not more than once in 20 battles, even with E&D fully researched.Ī Trickster will also hide the exact division strength of his formation. When a successful Surprise has occured, combat efficiency of the opposing forces is reduced by 20% and it will read 'Surprise' in their combat details pane.
I also do not know whether Skill Level of the Trickster leader is having an influence on the probability of a Surprise occurring. Exact figures, however, apparently are unknown (at least for HoI2 version 1.2). This chance is further influenced by how advanced your own industrial research of Encryption and Decryption (E&D) technologies is relative to your opponent. somewhat tricky: It increases the chance that the combat event Surprise will occur, on offense as well as on defense.
