Collateral dmg promo question

So, I can't remember the actual promotion name, but its the one you would give to seige units to increase thier collateral damage ability.

I have noticed that it was available to tanks and modern armor as well, so in my current game I thought I would make some of my tanks (promoted later to MA) the first two collateral damage promos so I could do a true blitz war and leave the artillery at home. Well I didn't get to use my tank army until the same turn I discovered composites, so I upgraded 43 tanks to MA and head to war.

My Modern Armor are not doing any collateral damage to units in a city with infantry, SAM infantry, and anti-tank units. Is this normal? Can modern armor and tanks not actually use the collateral damage promotion even though it is open to them? Is this a bug?

I am playing version 3.17
thanks

In v3.17, armored units can still receive the Barrage promotions, but don't cause collateral damage.

Collateral damage was removed from tanks and modern armor in BtS version 3.17.

That's because it was not supposed to work that way, it's a bug. They did some recalculating with the way collateral damage worked and as a result any non-siege unit can no longer do that type of damage. If you get Solver/Dresden's Unofficial Patch, you'll have two options. You can have collateral damage with your Tanks again, though less than what it was before, or you can just remove that promotion from the Armour unit line completely. You can find the patch over in the BtS forum, stickied up top. Be sure to go towards the end of the thread where you'll find Dresden's updates. The current version is 0.21 but Solver hasn't done anything with it since 0.19, which is what appears on the first post.

Except for the Chu-ko-nu

That's because it starts with collateral damage. Any unit that doesn't begin with it as an ability is unable to do that type of damage in 3.17, even with the promotion.

I know I was just being a douche and sharpshooting you on the "non-siege" statement. Technically the chu-ko-nu isn't siege, it's an archer.

Thanks for the advice, I may just do that. From what I have heard Solver's patch is worth getting. It makes sense to me that tanks should do a little collateral damage, definately not as much as artillery though.

It is a long gap between tanks and Mobile Artillery. It is tough to do a blitz war without seige units of some kind, although bombers are useful if the AI doesn't have fighters yet. If they do you are hosed until guided missles (which I just discovered the most excellent use of in a recent game)
