How to attack siege weapons?

[Sir Fartalot]

Remember in Total War: Rome we can attack to siege weapons and destroy them like ram, ladder, tower etc.
I wonder how to do same thing for Total War: Rome 2 Emperor Edition?

You can set fire to them with flaming ammo, even cause them to collapse I think.

^yup, or have your own siege weapons attack their weapons - also setting it to fire works.

But when i attack with flaming ammo or ballistas, my soldiers trying to kill the enemies who using siege weapons.

[Belfalas]

Even if you click directly on the siege weapon?

[Sir Fartalot]

Exactly, even if i click directly on the siege weapon.

Wish we could torch them like a gate. I had trouble trying to collapse a siege tower that made it to the wall a few % points away from lighting up by fire arrows.

I've noticed players get far better use of archers just by keeping them on the ground and fireing up at the men on the wall. It's so highly effective it makes towers and ladders suicide. Best to only attempt breaching with artillery. I don't put missiles on the wall anymore.

Get the impression that Fire Damage was intended to work differently pre-Release than it does now. Best guess is that flamables were supposed to catch fire - and then burn on their own for increasing damage until the "Fire HP" were consumed and the structure destroyed. Instead, we just get another set of HP to "Fire Hit" through.
Seems I recall that on Release Day, ships did indeed "catch fire" and very quickly burn up all their "Fire HP". But can't say that for the Siege Engines, well, because the AI never built Siege Engines - as they instead always Torched the Fire HP of the Iron and Stone Gates.
As it stands, it seems that Fire Damage appears "collateral" to damage to the troops manning the engines; and that the Engines themselves are not directly targettable. The closest you can come to taregetting them is with Aritllery - which you can aim at the ground. In this respect, Artillery is the best way to take out Siege Towers and Rams - especially with fire ammo - which seems to do extra normalish damage - but nominal fire damage /shrug
