Hey Falcon988!
I would suggest that you get Unnamed Obsever and Mortar addon. The observers spot out to around 1000 meters and will call in artillery on any enemy units spotted. He has made standard east and west units, as well as WWII and Nam Pack units and mortars. I PMed him recently and suggested that he also make some Ranger, BAS Tonal, MAP, Edge's resistance units, and some newer Russian versions and he sounded willing to do so as well as releasing an update to fix a few minor bugs.
In addition to spotting for artillery, they will allow MGs and snipers to engage out to around 500 meters! This will seriously change the way you cross open ground when using his great addon!
At some point CoC may be able to implement the observers into their UA and then we will have some true artillery, counter battery and seek and destroy type missions that will allow the use of AI indirect fire!
