Warhammer 40K Tactics

Then we have a Hammerhead's Railgun. It has 66% chance to hit. Against an AV14 vehicle, it then has to roll a 4+ to cause a penetrating hit, so 33% of a penetrating hit. A further 4+ is required to destroy it, halving the chance again to 16.5% chance of success. Much better than a Vindicare Assassin's rather low chance. And it can fire again if it misses next turn.

Even better is a Broadside with the targeting array. 66% chance to hit but all misses are rerolled, so 66% of the misses are successes. 88% chance to hit, 50% chance to penetrate, 50% chance to destroy brings us to 22% chance of success. And, as before, it can fire again if it misses and it is also considerably cheaper than a Vindicare Assassin or Hammerhead.

So, with this in mind, I still submit that the Railgun is the most reliable anti-tank weapon when you factor in its lack of extra dice, maximum firepower and 72" range. I don't know why I calculated that out, I just felt like it.
