3.B flexible mounted in skirmish form
3.B.5 says they stop and take a Kab at the table edge
Question
1. Is this any edge?
3 B 5 in full says "5. Are forced to run away or skirmish as SuGs but do not flee off table, instead stopping and taking a KaB test. If caught by a charging TuG they fight rather than disappear."
So they only stop and take a KaB if they would flee off table if a SUG.
SuGs only flee off their own rear table edge.
