If you’re new, read the guide provided by the developers then these:
To add a constant artillery fire in at a coordinate, with given radius you can use,
artillery_strike_requester :

spawnPeriod is time between calls
StrikeTemplate doesn’t need to be changed. But other templates can be found in the array below it.
To change radius, copy the codes to entities.blk: (explanation about the entities is inside code as comments):
artillery{
  _override:b=yes
  _use:t="replicating"
  artillery_zone__radius:r=240.0 //radius of where shells can possibly land.
  artillery__dispersion:r=240.0 //smaller or equal to radius. radius of where shells WILL land with dispersion
  artillery__adjustmentDispersion:r=24.0
  artillery__shotsDone:i=0 //dont touch this
  artillery__shotsCount:i=160 //shots per call
  artillery__adjustmentsShotsCount:i=3
  artillery__timeToFirstShot:r=10.0
  artillery__nextShotTime:r=-1.0 //-1 to disable. shooting speed is dependant on fire rate of the artillery_gun below.
  artillery__timeBetweenAdjustmentsShots:r=1.0
  artillery__timeBetweenShots:r=0.6
  artillery__gunTempl:t="artillery_gun"
  artillery__autoShootTempl:t="auto_shoot"
  artillery__adjustmentGunTempl:t="adjustment_artillery_gun"
  artillery__sourcePos:p3=0.0, 0.0, 0.0
  artillery__targetPos:p3=0.0, 0.0, 0.0
  artillery__calledByTeam:i=0
  "artillery__callerEid:eid"{
  }
  "artillery__offender:eid"{
  }
}
artillery_gun{
  _override:b=yes
  _use:t="tankgun_76mm_l11"
  _use:t="hit_effect_group_artillery"
  gun__ammo:i=111 //i believe this should be equal or greater than shotCount in the above entity
  gun__maxAmmo:i=111 //same
  killLogName:t=""
  item__name:t="Artillery"
  gun__blk:t="content/tanks/gamedata/weapons/artillery.blk"
  gun__locName:t="Artillery"
  gun__shotFreq:r=0.1
  artillery__calledByTeam:i=0 //0 should damage both teams. 1 should not damage team 1 etc.
  "gun__shellsAmmo:array"{
    ammo:i=111
  }
  "gun__ammoSetsInfo:shared:array"{
    "HE:array"{
      "shell:object"{
        blk:t="content/tanks/gamedata/weapons/shells/ussr/76mm_artillery_he.blk" //path to shell.blk.
        name:t="76mm_of_350m"
        type:t="he_frag_tank"
      }
    }
  }
  "gun__offender:eid"{
  }
  "gun_sound__shotPath:shared:object"{
    _tags:t="sound"
    enemy:t="enemy/weapon/cannon/artillery"
  }
  "artillery__callerEid:eid"{
  }
}
To edit the shells the artillery_gun fires, you should search for shells inside the datamine resource.
Example: Let’s make artillery strike spawn 12, 1000lb bomb explosions in a 120m radius every 120 seconds.
First, we edit the entities
- artillery_zone__radius,
- artillery_dispersionto 120.
Then we search for the 1000lb bomb in the datamine: (You are exclusively looking for BLKX files.)

Copy that file to your scene folder, and rename extension to BLK. The BLK can have any name you want. I decided to rename it to 1000lbspam.blk :

Inside artillery_gun entity, change the shell file path so it points to the BLK you just copied:
....
"HE:array"{
      "shell:object"{
        blk:t="%ugm/1000lbspam.blk" //%ugm is relative path to scene folder.
        name:t="76mm_of_350m"
        type:t="he_frag_tank"
      }
...
Open your scene, place down artillery_strike_requester where you want it, and open the properties tab:
change spawnPeriod to 120.

Done. entity should spawn 1000lb bomb explosions in the designated area. Which is the entity + radius You defined.
Not all shell or bombs will work. Some may behave differently than expected.
