Rob Beattie, the man who brought us the phrase "Kursk by GASLIGHT", has come up with an alternative vehicle damage table for use with "Battles by GASLIGHT".  He tells us "It was actually from a group member who played some Civil War naval game where 100 things could happen to your ship and thought that would be more fun that just 20."

While this was written mainly with "Battles by GASLIGHT" in mind, it would work well for regular GASLIGHT games too.  Ignore the difference between Penetrating and Catastrophic hits and roll once on this table for any hit that penetrates armour.  Results that refer to damage columns should be counted as medium artillery hits.
