Indirect fire support systems are weapons that do not require a direct line of sight to their target and primarily use the trajectory of their projectiles to engage the enemy. Mortars and artillery fall into this category because they are designed to fire projectiles over obstacles and are capable of delivering explosive fire from a distance. Mortars are typically portable and can be set up quickly, while artillery is often larger and mounted on vehicles or fixed positions. Their effectiveness in providing firepower from a distance makes them essential components of indirect fire support operations.

Other options, such as rockets and missiles, might also be capable of indirect fire but do not fit the classic definitions as closely as mortars and artillery do. Helicopters and tanks are direct fire systems that require line of sight to engage effectively. Additionally, machine guns and rifles primarily rely on direct fire capabilities and are not classified under indirect fire support. This distinction is critical in understanding the support elements available in a tactical environment.
