Outfiting a Dreadnought

Ok, here is the Scenario:

Space Marine Dreadnought

Outfit A - Multimelta/Heavy Flamer

Outfit B - Assault Cannon/Heavy Flamer

Will be landing via Drop Pod, looking to at a minimum glance a AV12 or less on deployment.

My argument falls with the MultiMelta, because of the strength as opposed to the multi-shot/rending from the Assault Cannon.


I am pretty decent at math, but I will probably screw this up, so let me know any errors I make.

Tournament Day:

3 Games, 3 Drops.

Assault Cannon - Heavy 4
Giving a total of 12 shots over the course of the whole tournament.
With a BS4 that is 66.67% of hitting.
So that is 7.92 shots hitting over the course of the day.
Needing a 6 (16.66% on a D6) to glance/penetrate.
That leaves 1.31 shots that glance/penetrate.

Multimelta - Heavy 1
4 Shots over the day.
Same as above for hit percentage.
Total of 2.66 shots hitting the target.
With a STR8 will need a 4 on 2D6 to glance. (with the drop pod I will assume I wont scatter out of the 12" Melta range.)
Here is where my math gets shady because of the 2D6, thinking its a 75% to get a Glancing hit and a 66.67% to get a penetration.
That is 1.99 shots that glance and 1.77 shots that penetrate

+ the Multimelta gets the extra 1 for damage.

Just really looking for someone to correct my math if there is any need to. I just want to pop a Rhino, Chimera, etc or stun a bigger tank Leman Russ, Preadator, etc for one round of shooting till I can possibly get to it in h-t-h.

Thanks in advance for any responses...

Your odds of getting a glance are 91%
Your odds of getting a Pen are 83%

Assault Cannon v Lascannon v Multi-melta: Statistical Analysis

Again good find John.

We really REALLY need to give the "power of the sticky" to mods ..

Top site guys

We can sticky, but only in the Section you moderate, I can do Vassal stuff and you have Fantasy privileges I am thinking.

What's the difference between the Twin Linked LasCannon on that link and the Tank Hunter? Was Tank Hunter a really old option in the Space Marine codex?

Yeah was a 4th Edition trait you could give Marines and other various units had it, Eldar Fire Dragons, Ork Tankbusters, etc.

Tank Hunters: (4th Ed. Rulebook)
Tank Hunters are especially skilled at finding and exploiting weaknesses in the armor of enemy vehicles. They add +1 to their Armor Penetration rolls whenever they hit a vehicle (with any weapon), and automatically pass Morale checks caused by Tank Shock.
