Mortars (60mm to 120mm)
Most modern mortar systems consist of four main components: a barrel, a base plate, a bipod and a sight.
Modern mortars normally range in calibre from 60 mm (2.36 in) to 120 mm (4.72 in).
Modern mortars and their ammunition are generally much smaller and lighter than artillery (such as field-guns and howitzers) allowing them to be transported by personnel without vehicle assistance.
Due to its high, parabolic trajectory with a near vertical descent, the mortar can land bombs on nearby targets, including those behind obstacles or in fortifications, such as light vehicles behind hills or structures, or infantry in trenches or spider holes.
