RULE 13
2. Calculating the Fire Effect
For each artillery piece, throw two dice: a score equal or greater than the number of hexes to the target plus two is required to obtain a hit. For example, at three hexes range a score of five or more indicates a hit.
Whenever a double one is thrown, a mishap has occurred. Throw one dice and consult the table below to determine the event.
| Score | Event |
| 1 | Gun damaged: roll 1D6 per turn, scoring a total of 7+ to repair. Gun cannot move or fire until repaired |
| 2 | Accident: one gunner killed or incapacitated |
| 3 | Interruption to ammunition supply: cannot fire next turn |
| 4 | Severe smoke: subtract 2 from 'to hit roll' on next turn and 1 on turn after if remaining in hex |
| 5 | Smoke: subtract 1 from 'to hit roll' on next turn if remaining in hex |
| 6 | Misfire: no other effect |
