bartkusa released an Artillery Battery Officer script on the BI forums.
The download comes with an example mission as well as the source of this script. Please refer to the download page how to use this demonstration!


Quote bartkusa :
I play a lot of ArmA multiplayer, and I really like using the Artillery Module to aim mortars at targets spotted by other players. However, I found that I wasn't happy with the amount of firepower a single mortar offered me, and there was no way to have, for example, AI subordinates shooting their own mortar tubes. Also, multiplying the number of explosions you drop is always more fun.

With this pile of scripts, you can order AI subordinates to man indirect-fire weapons, mimic your own gun azimuth and elevation, and fire coordinated volleys for effect.

You'll need to use the built-in Artillery module (or some other addon) to aim the battery. You could also use the Construction module to allow players to place their tubes where they want. All these scripts do are coordinate aim and coordinate fire.
