{{Info|'''Artillery shells''' serve as ammunition fired from one of the three mortar types ([[mortar|Explosive]], [[Incendiary_Mortar|Incendiary]], [[EMP_Mortar|EMP]]). They are also a requirement to build improvised explosive traps ([[IED trap|explosive]], [[IED incendiary trap|incendiary]]). They can be crafted at a [[machining table]] for 10 [[steel]], or bought from [[trade]]rs, typically the combat supplier. An artillery shell will explode in a 5 x 5 square if damage reduces its hit points to 20 or less, or [[deterioration]] reduces them to 0.}}
