how do you aim with artillery?
-
erm... if you have a well made FOPK (fire overhead protection kit) then maybe still can lah... if not... good luck...

s|nNeD, you forgot to mention that 155 can also do direct fire role, and that the process of calculation is through the Sharp calculator...Det 3 usually the ranging gun and Det 2 is the illum gun... am I right?Originally posted by s|nNeD:should i actually tell you how? coz i come from the artillery vocation
i guess i should
its a complicated process but i will just tell you the outline of it... firstly there must be a process called ranging to be carried out first... like zeroing of the rifle, ranging is done so that the rounds would land on the target... for this we need "eyes" to observe the target area and hence Foward Observers or in short FOs are needed to observe on the target... FOs would give the target grid of the target by reading it off the map. Then the GPOs (Gun positioning officers) would calculate the line and the quadrant that the howitzer should fire on. So when the artllery howitzers fire off their rounds, we give corrections to adjust the round closer to the target and then GPOs would then calculate the new line and quadrant that the howitzers should fire on...
Basically thats abt it but there is more to the process
cheers...
anyway just some extra info for you, Artillery unlike small arms hits an area target and not pin point target so there is no need for pin point accuracy... one artillery round (155mm calibre) covers and area of 150m by 150m. I heard that the FH2000 can fire ERFBBB rds, but it cannot sustain that kind of fire for a long period of time...something about burning out the barrel and jolting the gun sight outta alignment, is it true?
In Thailand, I saw the locals scurrying all over the impact zone looking for scrap metal after every fire mission...dangerous work man....one guy actually picked up a 120mm illum blind the other time and it was in the basket of his Honda Cub....rode alongside us as we were heading back to Sai Yok, shouting "Singapore Good!! Singapore Good!!" Needless to say, we were scrambling for cover and our helmets in the rover (not much anyway)... -
tt is if the rd directly impacts the spot.Originally posted by Nothingie:hard to imagine 1 arty rd can create a crater of 75m...
then our hand-dug foxholes any gd against arty fire?
more often than not troops are maimed by the shrapnel and stuff thrown up and the indirect impact. this the FT can help lessen and protect. -
i see yet another artillery person...Originally posted by Tango1:s|nNeD, you forgot to mention that 155 can also do direct fire role, and that the process of calculation is through the Sharp calculator...Det 3 usually the ranging gun and Det 2 is the illum gun... am I right?

Needless to say, we were scrambling for cover and our helmets in the rover (not much anyway)... yeah... 155mm can do a direct shoot with another scope... but seldom we do this coz this onli means that the enemy is within a few hundred metres away from us already... Erm... the sharp calculator is not as used as the pass already... new something that is classified... yeah normally gun 3 is the ranging gun and one thing is tat i have never seen a 155mm illum before... normally when we do l/f, it is the 120 mortar platoon that supports the illum round...
those that are in red i can't realli comment abt it coz i am not trained in FH2000. i am FH88 trained... and i belong to the liaison side of artillery...
yeah normally after every l/f, the villagers would scurry into the impact area to collect the scrap metal... can sell and make money mah... -
I went up to the impact area in Phillipines during a joint ex with their army. The impact crater is about 1m in diameter and 80 cm deep.Originally posted by SingaporeTyrannosaur:You are serious? The amount of explosives packed in a 155mm shell can create a 75m crater when a 9-ton MOAB can barely scorch 200 meters? -
of wat? the artillery shell or the MOAB?Originally posted by SPIKER:I went up to the impact area in Phillipines during a joint ex with their army. The impact crater is about 1m in diameter and 80 cm deep. -
It FH-88 shell.Originally posted by s|nNeD:of wat? the artillery shell or the MOAB?
There were also some 60mm motar shells fire by the philliphine army and my friend manage to pick up a blind without knowing it was a blind. luckily it did not explore. -
Sure???Originally posted by s|nNeD:Erm... the sharp calculator is not as used as the pass already... new something that is classified...
I just now saw a big bunch of calcs being brought in for reprogramming...
There's a whole lotta types of shells avail for arty... and there is a type of shell which gives lots of goodness out for later.
FASCAM they call it. Field Artillery Scatterable Area Munition.
Of course, there's more stuff being worked on overseas. -
To my knowledge, there's no such thing as carpet bombs. I think you've been confused by carpet bombing.Originally posted by laurence82:How about large arms like aircraft bombs (dumb bombs, carpet bombs, cluster bombs,Fuel Ordnance, mortar rounds, etc etc
Mortar round is technically part of artillery, and long long ago we used to have a Bn of mortars.
Fuel ordnance? I presume you mean napalm or fuel air explosives? The force from such devices... refer to "We were soldiers"
The most powerful area kill munition... has to be nuclear, without a doubt. 200kt W-80's anyone?

7.5 meters seems more reasonable on soft soil, and even then... it's kinda big...

DOUBLE POST -
sorry sorry... my mistake... i forgot... i just remembered that its 75cm... sorry sorry...
my apologies... ORD liao... -
that means total only 1.5m?!?!

impact diameter mah (but im not sure if its oni 1.5m)Originally posted by nismoS132:that means total only 1.5m?!?!
the danger area is 150x150m. tts wat matters. -
That isn't too hard to believe, this probably means that the arty shell explosion can throw out fragments to potentially wound or kill anybody in a 150m radius, esp when it is airburst. The total kill radius is probably a lot smaller.Originally posted by wuming78:impact diameter mah (but im not sure if its oni 1.5m)

There have been many soldiers killed by arty fragments which travelled a very long distance to tyco hit them in the head, it's just one of those things in war. -

So far the discussion was from the perspective of officers in an arty unit, concerned with FOs, GPOs, BROs, ranging and registration.
From a gun or mortar commander point of view, (from an M71 commander's experience, things might be more automated now) the BRO (recce officer) gives him a position to deploy, the direction (director reading). The layer sets the reading on the panoramic sight, the gun shifted so that it points to the required direction, then the weapon is emplaced. Aiming posts and collimator are then used subsequently for laying (aiming for you laymen :-) -
Oops forgot something. The 155 guns used can be used for direct shooting. For the M71 (I believe newer guns would use the same principle), a telescopic sight is used for direct shoot. The sight has lines that is used to aim the gun depending on the distance and speed of the target.
In my battalion, I think I was the only one who had done direct shoot before. It was easy because I was shooting at three stationary drums stacked up somewhere in Thailand. Of course I could see the impact for this case.
For indirect shoot, I was the only gun commander who had on many occassion seen impacts of 155 rounds in the target area (normally, only the FO and his assistant gets the chance). I was attached to the FO on one or more occassions (can't remember why). However, most of the opportunity came when I was involve in a weapon testing program in Thailand.
