Stock Bulge Scenario Question

[keif149]

Rick is correct and this designation for ES was used in many other titles that I own, however as I don't own them all I have no idea if it is universal ?

Thanks men for responding.

Some notations can be found in the designers notes, for example Minsk, about the "a" and "b" designations. I was unsure of the "s" until now however ;-)
