81 KRH 71 Y
81 KRH 71 Y (''81 mm kranaatinheitin malli 1971 ympäriampuva'', '81 mm mortar model 1971, 360-degree traverse') is a light mortar manufactured by Tampella for use by the Finnish Army. It is usually used to support the infantry by indirect fire, but it can also be used for direct fire. Each Finnish infantry company has a platoon of 81 mm mortars. The mortar platoon consists of three seven-man mortar squads, each squad manning a single 81 mm mortar. Jaeger Company M2005 has a fire support squad, which consists of two five-man mortar teams, both equipped with an 81 mm mortar. It can fire HE-fragmentation, smoke, illumination and practice rounds. Tampella also manufactured a static installed 81 KRH 71 RT (''81 mm kranaatinheitin malli 1971 rannikkotykistö'', '81 mm mortar model 1971, coastal artillery') for use in the Finnish coastal artillery fortresses. A newer version of the 81 KRH 71 Y with an improved baseplate made by Vammas is called the 81 KRH 96 (''81 mm kra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar (weapon)
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) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collimator Sight
A collimator sight is a type of optical sight that allows the user looking into it to see an illuminated aiming point aligned with the device the sight is attached to, regardless of eye position (with little parallax). They are also referred to as collimating sights or "occluded eye gunsight" (OEG). Description The basic layout of a collimator sight is a closed tube with a lens at its open end and a luminous reticle mounted near the closed end at the focus of the lens, creating an optical collimator. The reticle is illuminated by an electronic light source (an incandescent light bulb or, more recently, a light-emitting diode) or by ambient light gathered behind the reticle via an opalescent window or fiber optic light pipe. Collimator sights are a relatively old idea, being used in many forms for almost 100 years. Usage These sights are 'blind' sights; that is, they are used with both eyes open while one looks into the sight, with one eye open and moving the head to alternately ...

Tampella
Oy Tampella Ab was a Finnish heavy industry manufacturer, a maker of paper machines, locomotives, military weaponry, as well as wood-based products such as packaging. The company was based mainly in the Naistenlahti district of the city of Tampere. Until 1963 the company was called Tampereen Pellava- ja Rauta-Teollisuus Osake-Yhtiö (The Flax and Iron Industry of Tampere Stock Company). In Swedish it was called Tammerfors Linne-&Jern-Manufakt.A.B.. In 1993 the company’s forest and packaging business was bought by Enso-Gutzeit Oy. Tampereen Pellava- ja Rautateollisuus Oy was a company based on the merger in 1861 of two factories - a linen mill and foundry - situated by the Tammerkoski rapids. After a modest start it grew to become an institution employing thousands of people in the centre of Tampere alone, and more in its other units. In the 1950s the company's name was shortened to Tampella. The company went into decline during the 1980s and eventually went bankrupt in 1 ...

National Defence University (Finland)
The Finnish National Defence University ( fi, Maanpuolustuskorkeakoulu, MPKK, sv, Försvarshögskolan) is a military university located in Helsinki. The university trains officers for the Finnish Defence Forces and the Finnish Border Guard. The main campus is located in Santahamina, Helsinki. Prior to 2007, the school referred to itself, in English, as the National Defence College.

Initially it was established to train officers for the Savo Brigade of the Swedish Army, but soon it began to recruit cadets from all of Finland. The school continued operation even after the Finnish War in 1809, where Finland was ceded to the Russian Empire. However, in 1818, a fire broke out in the building, and the school was moved to Hamina to become the Hamina Cadet School. The Hamina Cadet School was trained officers ...

Indirect Fire
Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles. Description There are two dimensions in aiming a weapon: * In the horizontal plane (azimuth); and * In the vertical plane (elevation), which is governed by the distance (range) to the target and the energy of the propelling charge. The projectile trajectory is affected by atmospheric conditions, the velocity of the projectile, the difference in altitude between the firer and the target, and other factors. Direct fire sights may include mechanisms to compensate for some of these. Handguns and rifles, machine guns, anti-tank guns, tank main guns, many types of unguided rockets (although missiles, mortars, howitzers, rocket artillery, multiple rocket launchers, and artillery in gener ...

120 KRH 92
The 120 KRH 92 ( fi, 120 mm kranaatinheitin, malli 1992) is a 120 mm mortar manufactured in Finland. Due to major general Vilho Nenonen's initiative, Finland has built mortars since the early 1930s and although they have not been exported, the designs have been used in many countries. The largest technological transfer of Finnish mortar technology took place in the 1950s, when the technology was transferred to Israel for Soltam. The mortar is used to support battalions and companies in battle with indirect fire, to give support fire for infantry troops and coastal fortifications, and to apply smoke or illumination on the battlefield. It is usually transported by vehicle and the maximum towing speed is 80 km/h. The mortar is operated by a seven-man crew. Mortar has been observed in August 2022 in use in Ukraine as part of Ukrainian operations in Russo-Ukrainian War. Photos reveal 4 persons in crew. Their delivery was not announced by Finland.

Infantry generally consists of light infantry, mountain infantry, motorized infantry & mechanized infantry, airborne infantry, air assault infantry, and marine infantry. Although disused in modern times, heavy infantry also commonly made up the bulk of many historic armies. Infantry, cavalry, and artillery have traditionally made up the core of the combat arms professions of various armies, with the infantry almost always comprising the largest portion of these forces. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French ''infanterie'', from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' īnfāns'' (without speech, newborn, foolish), from which English also gets ''infant''.
