Ordinance Weapons Operating Manual..

[EternalEther]

Little question, seeing as my group has been a little fuzzy about a lot of these rules.

When shooting an ordinance weapon you need to roll to hit, then scatter, correct?

Nope, you place the template then scatter. 1d6 for LOS. 2d6 (pick highest) for no LOS

I personally think 4th edition made ordnance a bit too accurate. The 5" pie plate is almost guaranteed to hit your target unit if you have LOS every time. You have a 1/3 chance of it not scattering and another 1/3 chance to still hit the targeted model if it does scatter.

[Marneus]

The rules haven't changed from 3rd to 4th, they are just as accurate. Only in this edition, you can move and fire your ordnance weapon.

I thought most (if not all) ordnance weapons in 3rd edition were Guess weapons. At least the ones I used were.

Russ/Russ Demolisher/Vindicator
- May only do direct fire - fire at targets that they can draw line of sight to
- Roll 1D6 and Scatter Die if the vehicle was stationary
- Roll 2D6 (taking the highest) and Scatter Die if the vehicle moves

Basilisk/Defiler
- May fire indirectly (at targets that they cannot draw line of sight to) given they purchase their respective indirect fire upgrades
- May still do direct fire, even if they have purchased the indirect fire upgrade
- Direct fire, follow the rules for Russ/Russ Demolisher/Vindicator
- Indirect fire, may not move during the movement phase, and always rolls 2D6 (taking the highest) and Scatter Die for scatter effect

Whirlwind
- May only do Indirect Fire
- Indirect fire, may not move during the movement phase, and always rolls 2D6 (taking the highest) and Scatter Die for scatter effect

Mortars
(I don't think Mortars are equiped on vehicles anymore, they are just carried by infantry)
- Mortars are Heavy 1 weapons; they cannot fire if the infantry carrying them move.
- May only do Indirect Fire
- Indirect fire, may not move during the movement phase, and always rolls 2D6 (taking the highest) and Scatter Die for scatter effect
- (Side note, my gaming group has a house rule that if Mortars can draw line of sight to the target, they only roll 1D6 for scatter)
- If a unit contains multiple Mortars, then the Barrage rule is used - the first round scatters per normal limitations, the second (and third round) scatter by flipping the template in the direction of the Scatter Die (no D6 is used). If a 'Hit' is rolled on the Scatter Die, the player gets to choose which direction the template 'flips.
(Note that if a third Mortar is fired, it flips off of the position of the original Mortar, not the second one.)

Tyrannid Warp Blast
- I believe this is a direct fire only weapon, however -
- This weapon is not truly ordnance. It only uses the large blast marker to determine it's hit range (similar to the Tau Railgun Submunition), thus it doesn't follow the same rules as firing ordnance from vehicles, and the creature using it can move and fire it.

Biovore
(I see Biovores as the Tyrannid equivalant to the Mortar, follow Mortar rules)

Woah. . . No it uses the small blast. It's just a direct-fire Assault 1 blast weapon (except with the charged shot, which is not blast at all). If it used the large blast template I'd ignore the fact that my Zoanthropes miss so often. . .

The Tyranid weapon that uses the large blast template is the Barbed Strangler. Like the Warp Blast, it is just a direct-fire Assault weapon. It does cause pinning, but only due to its own special rules.

[Kirasu]

Yes ordnance is more accurate now, but you gotta realize that you lose the ability to fire *all* other weapons. Which is a big deal to a tank with 3 other weapons

Also dont forget that indirect fire has a min range of 36"

[Drake Dun]

Never in the history of wargames, was so much disinformation imparted to so many, by so few.

Let me strongly recommend to anyone reading this thread that they ignore it entirely and just READ THE RULES. Sometimes they are quite unclear but this is not one of those times.

It depends on the weapon .
baslisk and defiler is 36
IG motar and whirlind is 12
This is just few of them
So everybody needs to check thier codex and made sure.
thanks
