I have a few questions, and I figured it would be easier to consolidate them into one thread.

1) When attacking a Horde in melee, do you generate +1 hit for every two DoS (in addition to the base hit for passing the WS test), or just 1 hit for every 2 DoW?

Example: SM Bob attacks a Horde of gaunts. His WS is 50. Bob attacks, rolling a 30. Does he generate one hit or two?

2) Regarding multiple attacks: if a character has a pistol, ccw, and Swift Attack, he may attack up to three times (2 for SA, 1 with his pistol). If he only attacks with his ccw (using SA), then he strikes with no penalty to WS for either of his attacks. However, if he opts to also fire his pistol (for a total of three attacks), he suffers a -10 on all three attacks, correct? (This is assuming he has Ambidextrous and the Two-Weapon Fighter (Ballistic & Melee) talents.)

3) In MoZ, pg. 139, Detailed Method, in the Detailed Method section, it says that when calculating Attack Value, "add +1 for every attack beyond the first (additional weapons & twin-linked weapons count as additional attacks). The example given is for a Horde of guardsmen, and their bonus attacks are calculated based on their ranged weapons (+1 A for every 10 Magnitude). But what about a melee Horde, such as Hormagaunts? Do you calculate their bonus attacks based solely on their melee capabilities (+2 attacks because of Swift Attack, regardless of Magnitude)?

My thanks in advance.

1) That's +1 for every 2 DoS, in addition to the 1 for passing the test.

2) Correct.

3) Don't have the book right now, sorry :/

You would calculate melee hordes soley upon their melee characteristics. They will suffer for it yes, but lets see what happens in combat...

The guants are good melee fighters, 2 hordes of guardsmen and 2 hordes of guants square off. If the guants get into melee they are going to rip the guardsmen a new one, but first they have to cross the guardsmen's killzone. While they do this the guardsmen pour all the fire they can into them. When the gaunts finally get to the guardsmen there are only a few of them left in both hordes, while the guardsmen still have all their own numbers, and will likely beat off the remaining gaunts with little difficulty.

Send a man with a knife accross the room to stab the man with the gun, and the man with the knife will get shot.
