I stumbled across this when I was running the numbers for for a Assault cannon (Ass.C) vs a Autocannon (AC) and a twinlinked Autocannon (TLAC) when it came to bringing down transports. I firstly dont know the accuracy of all my math, i might be wrong if I am please point it out.
Firstly the Autocannon
Marines hit (2/3) of the time TL takes that too (8/9) and a Autocannon has 2 shots so its 2(2/3) or 2(8/9) will hit.
Different armour values come into play and possible damage, as well as Pentrating hits (Pens) and glances
AV10= Pen = 1/2 Glance = 1/6
AV11= Pen = 1/3 Glance = 1/6
AV12= Pen = 1/6 Glance = 1/6
AV13= Pen = N/A Glance = 1/6
Av14= Pen = N/A Glance =
If it Pens the most advantages results(s):
(1/3) chance of destroying them
(1/6) Immobilising them
If it Glances the most advantages result(s):
(1/6) Immobilising
So against AV10 Transport (against a GunTank almost any result is advantages even shaking them means they wont be shooting next turn, where as shaking a transport wont slow it down, stunning them might but instead of including this I have chosen to ignore it altogether.)
A AC has the following chance of inflicting and advantages result on a transport
(2(2/3)(1/2)(1/3))+(2(2/3)(1/2)(1/6))+(2(2/3)(1/6)(1/6))
=.37037 *100 = 37.03% Chance
A TLAC has the following chance of inflicting and advantages result on a transport
(2(8/9)(1/2)(1/3))+(2(8/9)(1/2)(1/6))+(2(8/9)(1/6)(1/6))
=.4938 *100 = 49.38% Chance
Note: before I continue, if someone could confirm that this math is correct if it isn't could you point out how to correctly do it. If it is correct again let me know ill edit this post to include the rest.
