I saw this on TMP. Very useful walk through. The only thing I didn't notice was how the SRM thingy works when shooting at contraptions with 'anti armour' weapons.
Good point Sterling, the abysmal Sustain/Start rolls on the part of the two vehicles really did cut down on the amount of vehicular gunfire in the game.
I did mention it once though, in Turn Four when the Ludwig fires at the Gun Truck...
Card #2 comes up as the Ludwig walker. Having failed to Sustain last turn, this turn it needs to roll less than its Start to move again, but fails to do so. Again the German player decides to fire one of its Main Guns, and this time hits with a roll of 4. The Gun Truck being only lightly armoured has a Save rating of 9, but the Ludwig's main gun is very good at penetrating armour, with a Save Roll Modifier of +4. So the British player needs to roll a D20, add +4 and get less than its Save rating of 9. The British player rolls a 12+4 = 16. A Penetrating Hit, but not quite enough for a Catastrophic Hit. Grumbling he rolls D20 on the Vehicle Damage Table and gets a 10 - “Random Weapon Knocked Out”. With two weapons to choose from he rolls a simple odds/evens with the result that it's the Gun truck's main cannon that's destroyed. Even if he manages to get the troublesome Gun Truck moving, he's now lost his best weapon against the armoured Ludwig walker.
So in summary, take the SRM value add it to the targeted player's Save
roll.... the roll, not the target's Save value.
So if an infantryman had scored a hit with a rifle with an SRM of -9, the targeted player would roll 1d20-9 for the Save roll. Hitting with a heavy cannon with an SRM of +4, he'd roll 1d20+4. A natural roll of 20 on the Save roll results in a Catastrophic hit (the Golden BB finds a chink in the armour and hits a vital steam line or something -
note that this seems to be a change from the original booklet in which a catastrophic hit happens if the modified Save roll is equal to or greater than 20)
Finally a reminder that SRM is only applied to vehicle armour, not Main Character Saves.
