The East Coast Highway (scenario 3) SSR say to place the 1st Marine Division (ROK) at the end of the "Reaction Movement Segment".
Looking at the Phase Map on the chart, is this the Reaction Movement Segment that occurs during the Initiative Movement and Combat Phase or the Reaction Movement that occurs during the Basic Movement and Combat Phase?
My copy of the GSR says "Initiative Reaction Movement Segment".
This is from v2.3. (January 2014)
