Using Arrow IV against airborne VTOL's

[midway]

What book are the rules for using Arrow IV against airborne VTOL's in?
Thank you.

Tactical Operations, the Flak rules are under the Direct Fire Artillery Rules.

You need Flack capable ammo, the chart covering artillery damage by ammo type provides that info.  It is mostly a straight up direct fire roll, adding your movement and things like woods, with a +3 in place of any enemy target movement modifiers.

You need Flack capable ammo...

There is no such thing as flak ammo for any Artillery weapon. There are Air Defense Arrows (those are meant for user against aeros, check the rules before using them against VTOLs), but all other anti-air shots are made using normal HE ammo.

I was referring to the ammo damage type codes.  Ammo types that have the F(lack) damage type codes are Anti-Air, HE, and Cluster for example.  If your ammo lacks that code, it can't be used for this type of attack, and the section heading it is literally titled "Flak".

Which is why I called it "Flak capable".

AA Arrow against a VTOL . . . if it hit the rotor it would still have a lot of its damage negated by the divisor?

Still better off with a LB-10X or even a -5X if that is the case, besides range?  Not really done a lot of A4 or tube AA practice even if I do include it in TO&E for that purpose.

5-point groups... four of them should be enough if they all manage to hit the rotor.

Does Arty used as flak not get the same flak bonus as LBX?  If they do, you should be getting pretty similar TNs, but with bigger clusters at vastly superior range, right?  (Though I’d prefer Thumpers and Snipers to Arrow, the ammo’s a lot cheaper and range is even better.)

Bigger cluster does not matter when it hits the rotor.

Flak artillery attacks dont target the unit, so no flak to hit bonus.  They're a dirrect fire attack at a hex at an elevation.  Maximum range of 17.

My random thought is if you can use the vertical splash to get a hit from above attack against a mech.  Or hit a height 1 unit hiding behind a level 1 hill.

TacOps errata 3.03 page 32: The player must declare that he is firing at the unit, and must have a valid line of sight to the target unit. Resolve the attack as normal for an artillery direct-fire attack, per the rules in Direct-Fire Artillery, at left (if the target is an airborne aerospace unit, the minimum number of hexes does not apply).

That rules out firing a flak attack at a hex at a particular elevation to try and hit a vtol that is hiding behind a hill. The rules say "No", although it should be possible, even going into the logic that it's a game since cluster rounds are going to be bursting over a targeted location on the map instead of after impacting the terrain. I guess VTOLs have it bad enough as it is.

Not in the sense that the other poster suggested. In a way its good that its in 5 point clusters since 15-25 single point clusters that all hit would be murder on a vtol. Then again, 5 point clusters are pretty dangerous to just about any vtol. :o
