Yes, a few of the missions have a -1 DRM during the mapboard determination DR. SASL 5 - Take the Highway, SASL 9 - Enemy Offensive, SASL 10 - Hold the Line, come to mind. There are probably a few others.SASL newb here: I am reading Chapter S and I noticed the A9 starts its DR with a 1. Did I missed a part where we apply a -1 to our DR such that 1 is possible?
