These explosives are used to mark high-priority targets for artillery support. They can only be used outside and within range of a C.A.M.P. settlement that contains a constructed artillery piece. If these conditions are met, the area marked by an artillery smoke grenade is bombarded with powerful explosives. Each artillery piece the player character has built will send five additional shots, provided that they are also within range. The grenade produces blue smoke and the grenade itself does not deal any damage.
- After constructing an artillery piece at a C.A.M.P., the yellow ammo box in the armory will continuously spawn 10 smoke grenades per day.
