Visualising DBA combat odds

DBA determines the outcome of combat by this method:
  • The attacker and defender determine their respective combat factors. These depend on their troop types, terrain, etc.
  • Each player rolls 1D6 and adds that to their combat factor.
  • The player with the higher score wins, often decisively if they double the score of the opponent.

The outcomes are:
  • Attacker wins and doubles the defender's score ("Attacker doubles")
  • Attacker wins, but does not double ("Attacker wins")
  • It is a draw
  • Defender wins, but does not double ("Defender wins")
  • Defender wins and doubles the attacker's score ("Defender doubles")

Below are various ways to illustrate the odds, based on the attacker and defender combat factors.

Numbers

This represents the possible outcomes as five numbers.
So, for attacker combat 4, defender 2, the table gives:
09|17|04|06|00
The odds for:
• attacker double = 9/36
• attacker win = 17/36
• draw = 4/36
• defender win = 0/36
