How to perform this type of attack?

[ThorBrasil]

I know it's obvious. Raise the nose of the aircraft to about 45 degrees and fire the rockets, but my question is how to ensure they'll land on the targets. How do I calculate the exact moment to fire at the target? Does anyone know?

Moment 1:05

You don't. You practice at a target range, and then memorise the firing parameters.

First of all, you never have a guarantee of hitting your target. It's expensive to fire at a target area with rockets. It's more intimidating, psychological warfare, and if you happen to hit something, you can only celebrate.
Simply put, you need to know the effective range of the rockets and calculate the distance to the target from which you should fire the salvo. Raising the nose improves the rockets' trajectory. They don't lose altitude as quickly. They fly in a parabolic pattern instead of a flat plane. In real life, there are also corrections for atmospheric conditions, but I suspect you don't need to do that in DCS.
So, for example, the rockets' range is 4km, you check the map for a 4km circle from the target. You fly on course to the target, arrive at firing range, raise the nose slightly 30°, and fire. Mission accomplished.

ps. Watch your speed and nose lift so as not to fall.

Use a chart like this to help mission planning. Either have a landmark or a unit with smoke to mark your pitch up point.

You indeed don't, as Raven said. Think less pinpoint attack (which is what we pretty much always need in DCS) and more area suppression.

Another thing to keep in mind here is that these kinds of attacks are not one-off missions, usually. Many of the unknowns and necessary corrections are done between the runs. Basically, you do this according to the table and then wait for the radio call on how your rockets landed and the next formation gets told: «Fire about 200m after passing that tree!»

Thank you all for the answers!
