Dreadnoughts fight in an assault in the same way as infantry. Resolve any hits scored on Dreadnoughts by rolling for armour penetration and damage as for a vehicle. As with other vehicles, troops are not allowed to dash round the sides and go for the rear armour of the Dreadnought unless they start their assault from the sides or rear. Each Damage roll that is inflicted on a Dreadnought counts as a single wound for the purposes of working out who won the combat.
There is one very important difference about Dreadnoughts in an assault. Dreadnoughts never have to check morale, and so will never fall back in an assault. Even if the Dreadnought has lost, count the result as a drawn combat. The only way to win a close combat involving a Dreadnought is to destroy it!
Dreadnought Close Combat Weapons. Dreadnoughts are often armed with enormous close combat weapons – hammers, wrecking balls, claws, etc. If a Dreadnought is armed with a close combat weapon it doubles its Strength in close combat (up to a maximum of 10) and ignores armour saving throws. In other words, for Dreadnoughts close combat weapons count as power fists, but it strikes according to its normal Initiative value instead of always striking last.
A Dreadnought armed with two close combat weapons gains an extra Attack just like ordinary troopers armed with two weapons.
