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. John Norris (2002). Infantry Mortars of World War II. Osprey Publishing. pp.42–43. ISBN 978-1-84176-414-6.

A modified version of the mortar, which fired a modern fin-stabilised streamlined projectile and had a booster charge for longer range, was developed after World War I; [13] this was in effect a new weapon. By World War II, it could fire as many as 30 bombs per minute and had a range of over 2,500 yards (2,300m) with some shell types. [14] The French developed an improved version of the Stokes mortar as the Brandt Mle 27, further refined as the Brandt Mle 31; this design was widely copied with and without license. [15] [16] [17] These weapons were the prototypes for all subsequent light mortar developments around the world.Mortars have existed for hundreds of years. They were first used in sieges. A European description of the Siege of Belgrade (1456) by Giovanni da Tagliacozzo says that the Ottoman Turks used seven mortars that fired "stone shots one Italian mile high". [4] The speed of these was said to be very slow. It was also said that men could be prevented from being injured by putting observers out who warned the troops of what angle the mortars were firing at. [5] mortar definition".

A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) [1] in high-arching ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition.Typical areas of use include health and leisure facilities, schools, universities, hotels, commercial, retail and industrial buildings.
