Which Tank?

That's always the hard part brother :D

If you're feeling a bit reckless you could be unconventional and go Cerberus. On a bad day it'll slowly rot itself away. On a good day, it'll blow apart anything you point it at.

The Cerberus just looks wrong to me, there are much cooler looking tanks available that a "rot-free".

The fellblade can't hurt a flare shielded spartan from the front, which, across a long table is where it's most likely to be hitting. Just saying. Go falchion.

How do you figure that? The fellblade cannon's AP rounds have armourbane. Going down to S7 isn't ideal. but with 2d6 pen, an explosion is entirely possible.

Missed that, well played. They still suck though.

Me being me I decided to calculate how much hull point damage a glaive and falchion will do on average vs. an unshielded super heavy vehicle. Both tanks' weapons uses rules that ignore vehicle armor values so they should be rather easy to compare.

Assumptions:
1. The vehicle being shot doesn't have any save of any kind. This simplifies the math a lot, but does mean that the added bonus from ignoring any and all saves when rolling a 6 with the Volcano Cannon isn't reflected in the results.

2. The Falchion is simply assumed to hit the target, which is mostly a formality, as it'd be really freaking hard to miss with a BS 4, TL, Massive Blast weapon. The Glaive is inacapable of missing alltogether.

 

Onto the simple math:
The Falchion's one hit will cause: (1/6)*0+(4/6)*D3+(1/6)+D6+6 number of hull points worth of damage which is equivalent to 2 and 11/12 hull points on average.

The Glaive will cause an average number of hits to a super heavy equal to 3, with each hit causing: (1/6)*0+(4/6)*1+(1/6)*((5/6)*1+(1/6)*2) hull points worth of damage which is 33/36 hull (about 0.861) points on average per hit, and 2 and 7/12 hull points together on average.

 

Damn, this was a lot closer than I thought, 2 and 11/12 for the Falchion vs. 2 and 7/12 for the Glaive.

 

One important caveat is that this only applies to when firing at a super heavy vehicle. Against normal vehicles the Volkite Carronade only scores a single hit and is vastly outperformed by the Volcano Cannon. Of course, the beam from Volkite Carronade could potential have burned through a couple of squads as well before hitting the super heavy. And then the volcano cannon hit might also completely annihilate anything next to the super heavy as well, and so on and so on...
 

Another important caveat is that this is using 6th edition rules. If any of the relevant rules have been changed with 7th, that would modify the results slightly
