I find the Random Events one of the best features of SASL, depicting the unpredictability of small unit firefights.
The document contains extra RE's that I use whenever the RE direroll is one higher than stipulated by the mission. (If mission stipulates RE DR 2-3, these are used on a DR 4)
Furthermore I find the OBA is ungainly so have speeded up the use by aquick and dirty solution described on the last page here.
