    I saw a military program showcasing the early developments of howitzer guns. The howitzer guns fire a shell from a location x which gains some acceleration velocity reaching a height h at time t covers a distance s by making a parabola. Upon reaching a certain distance it then gains momentum and falls as a falling object under its own gravity weight. The parabolic path is then measured by distance callipers which then adjusts the inclination of the firing howitzer turrent. The germans modified the howitzer concept to even firing nuclear shell in around ww2 days. Its fun to watch howitzer at work, there are small portable howitzer still to this date used in asian armies. The german then even invented the biggest howitzer gun and shell which was transported through rail lines. The germans engineering even developed to put the howitzer mechanism over a mobile armoured tank still seen in german army. British then developed bofors and american version developed self-loading howitzer quick versions.
    The physics of howitzer shell are projectile dynamics.
    So what i think is were howitzer mechanics were already studied, experimented upon in leonardo da vinci times. Thru ages there were many castles in europe countries which have now vanished. On over the castles there were many huge canons now their remnants and science manuals either put away or burnt by new generations. These had effective range, projectile shell burst power and might had be having mechanics too.
    So these science findings implementations were must had been the basic steps for the making of the howitzer modern day guns!

    You think, but do you have any reason at all to think it?

    Trebuchet. Catapult.

    Artillery Gun Module (AGM) Self-Propelled Howitzer - Army Technology

    I read some internet info about howitzers, their working principle is just like a cannon, with the rear bore opening a casing of shell is inputed and then a white gunpowder charge. The rear metal hinge is then closed, and the cannon acts like a combustible chamber with temp withstanding metal. Then the personnel pulls a thread and the gunpowder is charged and explodes. Which then actuates a opposite force which propels the shell outwards. When the shell moves across the turrent it again creates a pressure difference which moves backwards through the cannon howitzer turrent which moves the howitzer itself backward. This reverse pull is equated withstanded by some moving metallic bore cover over the turrent casing which moves thereby absorbing the shock. There are even pods attached which provides resistance to the ground for stopping the backward impact of the fired howitzer.
    Howitzer range on paper is written 10 to 25 kilometers. What if howitzers in real time of war are infact death inviting weapons fired just at a range distances of 100 meters to 1.5 kilometer maximum???
    What if small weapons like rifles range is too small just 200 meters and on paperwork stats its wrongly written.
    In real war as depicted in movie 'saving private ryan' the armoured tanks, troops, artillery fight just within 100 meter to 1 kilometer range??? even in present day scenarios!!!???

    long ago, when charging an enemy emplacement there was a brief respite between when you were vulnerable to cannon/howitzer fire, and before you were vulnerable to small arms fire.
    this wonderful eye of the storm(so to speak) was known as "being under the guns".

    I find it curious how the meaning of that simple phrase has changed its meaning.

    A howitzer is any cannon capable of being fired with the barrel elevated close to straight up. It is a realtively short range weapon. But the terms are not exact and overlap each other. Generally a "mortar" is the shortest barreled and highest angeled type of artillary, next came howitzers which were longer barreled and could be fired at a wide range of angels but mostly elevated and them there is artillery or Big guns" with the longest barrels and longest range. Field artillary is intended to be portable and fired in a more or less horizontal angle at a target that can be hit form the front or side. In modern armies the field artillery role is usually given to a "tank " of some sort.

    The exact meaning of each of these terms changes from war to war as technology changes. In the current US army there is a 155 mm self propelled gun that is a Howitzer, but it is also armoured and can drive to its firing site under its own power. I think its range is 5 to 10 miles. Prior to the american civil war (1860) a howitzer was a short barrelled smooth bored cannon used like a shot gun to repel infantry attacks with a functional range of under a hundred yards.

    Sealeaf, the Howitzer is Artillery.

    I served HHB 3-82 1CD, US Army.

    It is an artillery battalion.

    My job was to forward observe, line up the battlefield and call fire from Paladin Howitzer artillery support.

    This is no small puppy and not a short range weapon.

    No they didn't.

    Uh, yes.
    ALL modern weapons are developments of, and use, principles and science that were started/ discovered in times past.
    What's your point?

    It's certainly had variable meaning over time. By the civil war howitzers, the 12 pounders, easily reached a thousand yards and were often used to soften infantry lines. A splendid example of their attempted use was prior to the battle of little round top, where Confederate attempted to weaken a hole in the Union lines, but overshot them, instead and decimating support wagons and the ever present onlookers and journalist. If they'd been on target, Picket's charge would most likely have succeeded and perhaps changed Gettysburg into a Confederate victory that might have won the war. They are still used in modern armies ften range more than 30 km (especially with rocket assisted rounds), and often self-propelled, like the Palidine. Like the tank, there use is being increasingly replaced in large part by precision rockets, air power, and infantry tools to identified and guide smart weapons--regardless I think we'll continue to see them for decades in one form or another.
