The new vehicles rules in Rites of Battle include the most fearsome King of the Battlefield, the Land Raider. They look nearly impossible to stop as they have all-round armor of 50.
That 50 armor puts the Land Raider out of reach of many weapons. If my take on vehicular armor is correct, Righteous Fury only takes effect if you harm the Structure Points of a vehicle (ie, overcome its' armor) prior to RF coming into play. Here's a quick analysis of what has a chance of stopping one of these behemoths...
Astartes Meltagun: forget it. You have a 0.1% chance of getting past that 50 pts of armor at Short Range (where you get an additional d10 damage) - meaning you have to max out your damage roll just to do 1 Structure Point of damage (and have a chance of Righeous Fury'ing its' butt).
Astartes Multimelta: better than the meltagun. You need to roll 32 or greater on 4d10 (5d10 at Short Range) to get past the armor and into Structure.
Astartes Plasma Cannon: you actually have a chance with one on Maximal Setting but need to roll 28 or better on 3d10 to top the armor.
Astartes Krak Missile: again a tough proposition requiring you to roll 35 or better on 4d10 to get past the armor
Astartes Lascannon: much better. Rolling 31 or more on 6d10 is a pretty average result.
Astartes Conversion Beamer: your best bet past Short Range where you only need to score 25 or more on 6d10.
Astartes Melta Bomb: ETA; needs to roll 29 on 6d10, so about average to get past the armor.
Astartes Chain Fist: A Marine with a Str in the 60s would just have a chance of getting a point of damage through armor with an Exceptional Crafted Chain Fist if he maxed his damage roll.
Astartes Power Fist: As a Chain Fist above but would need a Master Crafted Power Fist and would have a harder time rolling the max damage needed since they lack Tearing.
Astartes Thunder Hammer: A little better than the Chain Fist if you don't take Tearing into consideration. That same Marine above could Pen the Land Raider on a max roll and a Marine with a Str in the 50s could do so as well if they had an Exceptional Crafted weapon.
Conclusion: If you meet a Land Raider you'd better have a Multimelta or, preferably, a LasCannon to chip it's paint! Meltabombs are your friends as well. If at all possible get a Conversion Beamer...
