Finally - after some hard work my kick-ass artillery script is ready!!
This is no bullshit where shells will appear out of nowhere, this is the actual guns (M119s) in ArmA aiming and firing their weapons. All you have to do is click on the map and you'll have artillery shells raining down there within a minute or so!

o3oDeath  also released an artillery script, but this script is significantly different as his script tries to emulate 'real' artillery.

This addon has a little bit of a learning curve and requires more than one person to effectively hit something at long ranges but that is how it is in real life.
And again, also this author has some tough words about his creation:

I got sick of all the click on map artillery scripts and wanted something a bit more realistic so I gutted the vanilla arma M119 and D31 and and reconfigured them with new ammo and magazine classes.and named them LRM119 and LRD31. There are 8 different powder charges.
The timetolive is set for 500 seconds so the round vanishing will not be a problem.
sidenote: if you want to find the ranges use a bullet cam script and you can follow the rounds trajectory. but at 4 km at a 35 degree angle it will take about 30 seconds to get there. But you can use this method if you want to fire it alone with out a spotter. Or just want to get the ranges of all the powder charges.

 Chops Has not released a script, but he has released his artillery as an addon! the  addon that allows M119 artillery strikes of four different warheads, through the action menu and mapclicks, out to a range of 7600m.  this addon features -M760 HE,  M916 DPICM, M84 smoke, M314A3 illumination

Why an addon and not just a script?

The standard BIS M119 ammo disappears after about 20 seconds (I think). In the (very sloppy) config of this addon, the timetolive has been increased, so the shells stay in the game long enough to fly further. In addition the initspeed of the default ammo wasn't enough to propel the shells very far. The init speed for CPS_arty ammo is 3500.
The field of motion of the m119 has also been increased in the config so it can fire in high angle trajectories, limiting the problems caused by mountains.
