A mortar is an artillery weapon which fires explosive shells. The shells are known as (mortar) bombs. They are fired at targets which are close, as mortars do not have long range. It has a short barrel which fires the mortar bomb at a low speed high into the air to reach its target. They have been used since medieval times. Mortars are made in different sizes, from large and heavy mortars to infantry mortars which can be carried by just one soldier. They are called an indirect fire weapon because the bomb drops onto the target from above, rather than being aimed straight at it. Soldiers firing a mortar do not need to be able to see their target. Fire Cement is a ready and mixed combination of thermosetting resins and inorganic fillers. When applied and exposed to high temperatures, this combination is capable of healing, which results in a mortar. This mortar is temperature resistant up to 1250ºC. The ammunition fired by mortars are properly called "bombs". One possible reason for this is that the fins that stabilise the round when it is flying, and the shape of the round makes it look like a bomb dropped from aircraft. [1] Toys". Culturecontent.com.

Mortars are not very stable if they are used on snow or soft ground. This is because the recoil pushes them into the ground. The Raschen Bag can be used to avoid this problem. Mortars can be very helpful if they are used in hidden places. It can be even more helpful if there are people around the battlefield that help tell the mortar where to fire (forward observers).

A mortar round could be aimed to fall straight into a trench because of the deep angle that the bombs fell at. FR230 is suitable for the following service penetrations: single and bunched cables, cable trays/ladders/baskets, non-combustible pipes. Also suitable for cable trunking, combustible pipes, insulated non-combustible pipes, in conjunction with a suitable Nullifire closer device (for example FP302 Intustrap or FS709 HP).Modern mortars and their ammunition are generally much smaller and lighter than long range artillery such as guns and howitzers, which allows light and medium (typically, 60mm and 81mm/82mm) mortars to be considered light weapons; i.e. capable of transport by personnel without vehicle assistance. During the Russo-Japanese War, Lieutenant General Leonid Gobyato of the Imperial Russian Army applied the principles of indirect fire from closed firing positions in the field and, with the collaboration of General Roman Kondratenko, he designed the first mortar that fired navy shells. Vesa Toivonen, 2003, From Tampella to Patria, 70 Years of Finnish Heavy Weapons Production, Tampere, ISBN 952-5026-26-4 FR230 may be used to seal apertures in the separating element up to 1100 mm x 1100 mm in a floor or wall (without additionnal reinforcement requirements).

Experts recommend using masking tape around the top and bottom of the seal so that a clean straight edge of the heat resistant cement can be applied and exposed to the heat. The Strix mortar round is a Swedish endphase-guided projectile fired from a 120mm mortar currently manufactured by Saab Bofors Dynamics. STRIX is fired like a conventional mortar round. The round contains an infrared imaging sensor that it uses to guide itself onto any tank or armoured fighting vehicle in the vicinity where it lands. The seeker is designed to ignore targets that are already burning. Launched from any 120mm mortar, STRIX has a normal range of up to 4.5km. The addition of a special sustainer motor increases the range to 7.5km. Israeli army tests GPS-guided mortar shell". i24news. Archived from the original on 2014-04-07 . Retrieved 6 April 2014. From the 18th to the early 20th century, very heavy siege mortars were used. These were very difficult to move around. These had up to one metre calibre. They were often made of cast iron. Smaller designs that were easier to move around were brought in during the First World War. Mortars are still used today.Norris, John; Calow, Robert (11 December 2002).

An infantry mortar can usually be set up and fired from a mortar-carrier. A mortar-carrier is a modified armoured vehicle or one built especially to be a mortar-carrier. They have a big hatch on the roof. Mortars with two barrels—like the AMOS PT1—are the latest kinds of heavy mortar. They are put on carriers such as armoured personnel carriers, tank chassis and patrol boats. [3] Chris Bishop (2002). The Encyclopedia of Weapons of World War II. Sterling Publishing Company. p.202.
