Arty Fire
-
looks like no arty fellow here to answer your queries. I'd say for dumb rounds, even 50m from initial impact is good enough.Originally posted by SpecOps87:Well, I was referring to not really pin point precision, but more or less say 20m or so from the impact of the first salvo.
Yeah, Air Assault refers to the Guards in SG context. Haha, thats what my friends already serving tell me. Its their deployment method and tactics which fascinate me, same as that of the AI.
remind me to ask you again when you're roughing it out rappeling down a heli or chionging out of the tank upon arrival at FUP... would you still be fascinated about the tactics and all. -
Haha, sure.Originally posted by sir sickolot II:remind me to ask you again when you're roughing it out rappeling down a heli or chionging out of the tank upon arrival at FUP... would you still be fascinated about the tactics and all. -
You are my idol manOriginally posted by SpecOps87:Nxt yr, aft I complete Poly den enlist, nw still guai guai schooling.
Not really into Arty as I don't really have a gd understanding of how they work. More into Air Assault Infantry and AI.

And why so?Originally posted by I_love_my_toilet:You are my idol man -
i've been to last yr's reservist exercise in thailand.. usually (for saf anyways) the time between each round is a minute or so to enable the FOs to note if the rounds landed on target..
the battalion did only one arty barrage during one of the nights there.. i.e. every 155mm takes a turn to fire for about 10 minutes.. and i can tell u it's really like hell on earth even from the firing ground.. u wouldn't wanna know wat it feels like to be on the receiving end
sidetrack a bit, i was like TS before i enlisted.. damn curious and interested in military stuff.. now i can't wait to get out of my no.4 this yr..
reason is simple: there are no wars to fight here.. most regulars i meet are only interested in keeping their arses clean and they can dump a load on nsfs from such a height that u won't know wat hit ya.. msd has raided my camp several times during my stint and everytime there's some sort of security breach at high levels.. it's always the low rank nsfs who get charged.. even when they don't have the access to those levels.. so consider urself warned -
Why? The lightning never strikes the same place twice too?
-
I even more noob thaan TS, need someone with patience to explain...
why is it a Arty round of 155mm causes much more damage over a wider area than a tank round of 120mm? (Let's assume they shoot straight, and the shells don't fall down from the sky) -
It is not that arty fire is unable to hit the same spot twice... it's just that the probability of that happening is very low. Furthermore, the concept of arty fire is area target: 75m by 75mOriginally posted by SpecOps87:Was watching Band of Brothers and am curious about one thing, mebbe guys from Arty can help with this.Is it true that like lightning, arty fire is unable to hit the same spot twice? Making the spot which was last hit safest as compared to those around it?
Thanks
But with modern technology, achieveing multiple hits for the same target is now possible.
Arty rounds travels a great distance before reaching the targets. For low charge firing, the distance is from 5 km onwards. The FH2000 has the furtherest range of up to 40 km. Unlike firing a rifle where u can see the target, arty battallions reply on FOs (Foward Observers) to tell them the coordinates of the targets. These FOs are also known as the Eyes.
As the range increases, the accuracy of the rounds will suffer. This is becos the shells are subjected to various weather conditions such as wind, density of air .... etc. Even the rotation of the earth and gravitational pull plays a part too. The weight of the shell is a factor too and often, the shells used are of different weight,. Other factors will be the accuracy of the coordinates of targets as FOs usually rely on visual spotting.
Usually for Arty, the FO will use a reference point as the initial target. He will do ranging (ie: zeroing) where he will move the rounds thru various corrections to the reference point. Once the arty guns are "zeroed", he will then have then call for fire on the "real target". This will increase the accuracy and ensure maximum devastation.
I was lucky to be in arty but was even more fortunate to be a Gunnery Spec. Unlike the Arty Specs whom are the gun commanders, GS do not learn how to operate the guns. But we learn about the science and physics of arty. Believe it or not, one of our SOP equipment is a scientific calculator.....
Hope my answer clears up some doubts which you may have! -
till now no FO, FM or even any arty guys in here giving reply?
BN level used to have 81mm and now all change to 120mm but CDOs still using it. (much earlier we have the 60mm)
1st round a norm white phosphorus round for FO marking.
estab neut, part re-neut and final neut all are given fire order during planning.
"support" arty fire are fire request during engagement. a norm will be 10 round mortar fire but 1st round still WP for marking.
anyone saw the drop shot photo and the round explode in the barrel in SIW?
anyone saw the photo taken in NZ on the 155?
heard of anything on mortar drop shot just 10M away from the barrel?
slow in loading.
-
the NZ accident occured 1 batch before me. But i was in the same unit as them, 23SA.
Poor commander... had his face blew off becos of a faulty fuze. I saw the photos of the accident while doing some paperwork for my S3. It was not a pleasant sigh....
-
All along I thought we talking about howitzer and not motar fire
-
I have always been impressed with artillery but i don't really know how they operate. Reading some of the info here expanded my knowledge. TS will be enlisting in '08?
If given a chance i would like to go to arty. but no more chance le. -
do saf uses those round that can explode mid air as in explode 2 meter above the target?
-
I would like to provide an answer to this question, abeit, a theoretical or scientific one since our friend is going to the polytechnic before doing NS. The point of impact of the projectile can be calculated theoretically using particle mechanics (physics). I think 'O' level physics still has mechanics and I remembered that there was an example or question in physics textbook or ten year series to calculate the distance a cannon ball could reach if fired at a certain velocity. Therefore, knowing the weight of the projectile, the force acting on it (from the firing of the charge), the angle of elevation of the gun (or tube for mortar), it will be possible to calculate the direction vector and the possible impact point of the round. Of course, wind conditions (direction, speed) and air density (humidity) will have effect on the forces acting on the round while in flight. Thus, if everything remains constant, theoretically speaking, every single round will hit the same spot.Originally posted by SpecOps87:Was watching Band of Brothers and am curious about one thing, mebbe guys from Arty can help with this.Is it true that like lightning, arty fire is unable to hit the same spot twice? Making the spot which was last hit safest as compared to those around it?

This, I suppose, refers to air burst round using time proximity fuse.Originally posted by mr_sotong:do saf uses those round that can explode mid air as in explode 2 meter above the target? -
Arty rounds cant hit on the same spot even 100 rounds is given by a single gun with the same target grid.Originally posted by SpecOps87:Was watching Band of Brothers and am curious about one thing, mebbe guys from Arty can help with this.Is it true that like lightning, arty fire is unable to hit the same spot twice?

factors affect ;
weather, wind, temperature, rounds, gun barrels, re-coil impact of gun, layer, gun sight and many equipment factors.
arty target is always 150 x 150 or 100 x 100 area target. unless is linear target or defensive mission.
sorry, forgot alot of terms used as now MR liao
and the killing radius of a round, so no SPOT is safe within the 150 x 150 area target ( just saw someone mention 75 x 75 ) -
maybe because the 155mm round is bigger than 120mm roundOriginally posted by chanjyj:I even more noob thaan TS, need someone with patience to explain...

155mm gun round killing radius is bigger than 120mm mortar rounds. -
why not, got underground tunnelsOriginally posted by storm_freaky13:yup those smart munitions.
but i doubt the commanders want to constantly arty the same spot over and over again!
-
Of course all rounnds will land within the area target given . Arty always said, ON TIME ON TARGETOriginally posted by SpecOps87:Alright, lets say that all else remains constant in terms of the equipment, Arty caliber say 155mm, shells used is High Explosive. Read that the "effective" blast is approx. 100m, so lets say that 2 salvos of 4 rounds from 4 guns are fired, is there a high chance for the rounds to all land within the same area? Given that a competent FO is tasked to watch the fall of the rounds? -
MOVE LIKE LIGHTNING, SOUND LIKE THUNDEROriginally posted by deadbeat:Kings Of the battlefield = arti -
last time arty family inclued 81mm mortar, 120mm mortar, 160mm mortar, 105mm gun, 155mm gun.Originally posted by chanjyj:All along I thought we talking about howitzer and not motar fire
now arty unit is basically 105mm and 155mm gun. all mortar given/pass to infantry
so mortar and gun area target is same and function is same.
i am from last batch 120mm mortar battalion aka former 22SA. -
of all support unit, arty is best, caused every where you go got 3 toner to sit, no need to walk accept siong on deployment only
-
If you are referring to tunnels then i dont see how you want your shells to keep landing on the same spot.Originally posted by Quiet Guy:why not, got underground tunnels
By spot i mean the exact impact location which is what TS was asking about anyway.
Perhaps you meant spot as in 100x100. I am not sure.
If not, how are you going to take out underground tunnels with artillery shells landing at the same impact point all the time? Tunnels afterall cover a wide area. -
Sorry than, we are refering to different SPOTS.Originally posted by storm_freaky13:If you are referring to tunnels then i dont see how you want your shells to keep landing on the same spot.

I was referring to the 120mm round coming out of tanks (like our upcoming leopards), not the motar.... was wondering why 155mm arty round casues so much more damage than a 120mm tank round.Originally posted by Quiet Guy:maybe because the 155mm round is bigger than 120mm round
155mm gun round killing radius is bigger than 120mm mortar rounds.
