Onko hinta/laatusuhde huonompi? kerrotko tuon Mjölnerin heikot puolet Suomalaiseen Amokseen verrattuna?

The rebels of the Free Syrian Army have introduced a revolutionary design of a weapon, a shoulder-launched mortar.
They simply took the concept of the mortar projectile and made it work on a smaller scale/caliber and then they manufactured a launcher to shoot it from the shoulder, the concept is similar to the Russian DP-64 which gives it several advantages in “hit and run” tactics.
Usually, a mortar crew is an easy target due to their stationary position in action while aiming, calculating, adjusting and firing; even when they fire from behind a cover since there is no maneuverability with a mortar (unlike small arms and man-pad rocket launchers).

But this design gave them the absent advantage in which they can carry, aim and fire and then disappear like all guerrilla warriors. Of course, it requires a well trained individual to operate it for fast calculations and adjustments in the battle ground.

Currently, the operators employ it as an anti-personnel grenade launcher but the reason behind calling it –revolutionary design- is that it can be used to hit the armored vehicles’ weakest spot by a top-attack similar to a Javelin ATGM. Considering the huge difference between the two payloads and destructive abilities (and the guidance system of course), hitting a Tank’s optical devices or hitting the cannon of a BMP armored fighting vehicle AFV would have the effect of disabling the vehicle and removing it from the fight, especially if the mortar shell is modified with a shaped explosive charge.
Another method of usage can be clearing rooms and buildings like the Russian RPO-A Shmel (again we are not talking about the destructive capability, or the state of art design or the mechanism of the Russian made weapon compared to this) but it has the same effect as throwing a High-Explosive grenade through a window from 300-400 meters range.

The launcher is made out of a tube and a spring loaded firing pin powered by side-trigger which makes it fire-at-will unlike the ordinary mortar that fires when the shell is dropped to hit the firing pin by gravity.
One of the disadvantages is the recoil generated by the energy of the thrusting shell, that tells us why they made it in a small caliber. Who knows if they will develop recoil damping shoulder pads to increase the capabilities of the weapon the future to have more capabilities than only a grenade launcher.

47-mm low trajectory mortar M/Kahva
(47 mm laakaheitin M/Kahva)



PICTURE: Prototype of low trajectory mortar M/Kahva. (Photo taken in Sotamuseo). CLICK THUMBNAIL TO SEE LARGER PIC (68 KB).


Low trajectory mortar designed by Major Kahva for Finnish Army in year 1942 was designed for shooting vision slots of enemy bunkers and machinegun nests with 47-mm mortar shells. This shoulder fired weapon equipped with a folding adjustable bipod and used normal Mosin-Nagant rifle receiver and bolt for firing 47-mm mortar shells originally introduced for 47-mm Tampella mortar prototypes in 1930's. Hence availability of the ammunition was not too great and while the weapon was equipped with bipod it was quite heavy and must have had considerable recoil. This weapon has simple iron sights on left side of the weapon with the rear sight loaned from M/28-30 or M/39 rifle. Sako Oy manufactured three prototypes, which were field tested, but the weapon was never approved and did not see later production.

Even if the design had not suffered the handicaps mentioned above, it had very little chance of success. Looking at the design it is fairly obvious that it was intended to fill the notch that was soon covered by recoilless rifles. Hence unfortunately the design would have become obsolete almost immediately anyway.




81-mm low-trajectory mortar m/Tampella
(81 mm kaasujarrukranaatinheitin)

Presumably intended to fire normal 81-mm mortar shells this low-trajectory equipped with recoil mechanism was developed by engineer H.O. Donner for Tampella, where he worked. Tampella manufactured prototype was tested by Finnish Army in Niinisalo test firing range, but the prototype proved less than successful. What is known the main problem was apparently with unacceptably poor shooting accuracy mainly caused by low muzzle velocity.




120-mm low-trajectory mortar m/Tampella
(120 mm kaasujarrukranaatinheitin)

Also this low-trajectory mortar was based developed by engineer H.O. Donner for Tampella during Continuation War. Tampella build at least one prototype which was tested in Niinisalo test firing range multiple times. Basically it was a 120-mm mortar barrel installed on gun carriage of captured Soviet 45-mm antitank-gun with its recoil system. The weapon was intended as possible direct fire weapon against bunkers and possibly as antitank-weapon, but proved unsuccessful. The main problems revealed by testing included gun carriage proving structurally too weak for weapon of this type and poor accuracy presumably due to low muzzle velocity. Test firing report from year 1944 also suggests that there were issues in developing properly working projectile and propellant combination.

Mitä vit?!? Korkea polviasento on ainoa oikea. Reidestä saa hyvän vastavoiman rekyylille. Ei osteoporoosin vaivaamille:p

Muistan kyllä yhden Korkeajännityksen, jossa valonheitinporukka tuhosi krh:n lonkka- ammunnalla kuorkin lavalta maahanlaskua tehneen Me 323 Gigantin.
 
Vähän kiinnostaisi onko ne britit ampuneet 2" heittimillään "läpällä" kuten tuo jenkki videossa vai jossain taistelutoimissa. Ja jos on tosipaikassa ammuttu niin miksi helvetissä :D Se että voi, ei aina tarkoita että kannattaa.
 
Omana palvelusaikanani tapasin sotilasmestarin joka oli ampunut 120 mm heittimellä lonkalta. Palveluskelpoisuusluokka ei ollut kylläkään A1 sen jälkeen...

Operaatio Market Garden. Arnheimin taistelussa. Syy tuohon ampumiseen oli se, että PIAT:sta oli loppunut ammukset joten sillä ei voinut ampua tulitukea. Ja taistelu oli vissiinkin kaupunkitaistelua. Huomatkaa kuitenkin, että lähde voi olla varsin värittynyt:

 
ELBIT_Spears_Mortar_mounted_on_BTR-70_armored_vehicle_001.jpg

BTR-70 varustettuna iippojen 120 mm SPEAR automaagisella kranaatinheittimellä.

This upgrade program was first highlighted by Azeri newspaper in August 2017. It then confirmed that SBS’s SPEAR 120 mm automatic mortar complex of Elbit Systems was being mounted on BTR-70 chassis.

Azerbaijan State Border Service's (SBS) BTR-70s are currently being modernized at the service's maintenance center. The vehicle with new engine and control system is indexed as BTR-70S.

The Elbit Systems SPEAR mortar system is equipped with cutting-edge fire control, navigation, automatic aiming and propulsion systems, which facilitate a fully-autonomous operation and provide increased fire power and accuracy (within 30 meters of the Circular Error Probability (CEP) radius. In addition, the RMS’’ advanced target data collection and identification capabilities enhance situational awareness and increase crew survivability. SOLTAM SPEAR is offered both independently as a standalone installation or as an integral part of a larger artillery unit or formation. It is compatible with all types of 120mm smooth bore mortar systems and munitions.

The Soviet BTR-70 8×8 amphibious armoured personnel carrier was shown in public for the first time during the November 1980 parade in Moscow. Around 70 vehicles were delivered to the Azerbaijani Armed Forces in 1991.

The hull of the BTR-70 is of all-welded steel armour construction with improved protection over its frontal arc compared to the original BTR-60 series. The standard version of the vehicle is fitted with one-man turret armed with a 14.5 KPVT and a 7.62 mm PKVT machine gun.

The engine compartment is at the rear of the hull and is fitted with a fire extinguishing system. The vehicle is motorized with a new Diesel engine KAMA-740.11.240 and improved transmission. The vehicle can run at a maximum road speed of 80 km/h with a maximum cruising range of 550 km. The original single water-jet at the rear of the hull is removed which would indicate that the vehicle lost its amphibious capabilities.

The troop compartment is to the rear of the turret with three firing ports and one vision block in each side of the hull. Between the second and third axles is a small door that opens to the front. The vehicle can carry a total of 10 soldiers including commander, driver and gunner.
