Im confused to how would TL weapons make you re roll misses?

wouldnt 2 shots = maybe re roll wounds / penetration instead?

Im clueless about military weapons and such, please explain to me -_-

The basic idea of a weapon is that you need to be able to hit the target, with a missile that will damage it.

In the real world this can be achieved by various means. One is explosive missiles that hit the target by fragmentation -- example, artillery shells.

Twin-linking was used for battleship weapons. The idea is to shoot a pattern of shells, usually a salvo of 8-12, that gives a statistical chance of hitting the target with a shell big enough to penetrate and do damage.

The other main use is for aircraft and anti-aircraft guns. Here you have a different problem. Aircraft move very fast but they have very light armour. The problem therefore is to track the target quickly and put enough bullets into the air to give a chance of hitting.

The bullets don't need to be very heavy but you need to fire a lot of them. Light calibre guns can easily be mounted on mult-barrel mounts that can track and shoot quickly.

So actually the GW idea of the chance to re-roll misses is quite a good simulation.

Anti-aircraft artillery has always consisted either of artillery batteries that shoot a pattern of shells timed to explode at a certain height, and hit by fragmentation. Before guided missiles this was the only way to hit high-flying aircraft.

Low-flying aircraft are best attacked with rapid-fire weapons. WW2 navies had AA weapons with as many as 8 barrels on one mount.

Modern AA cannons usually have 2, 3 or 4 barrels, or else a rotary cannon.

hmm i always wondered in WW2 movies, how do they figure out when the flak explode?

If the bomber saw the height of explosion, couldn't they quickly change the altitude?

Early in the war, the explosion height was done by time fuses, or by pressure sensitive fuses. If the target had several AA batteries they might fire a box pattern of barrage. In other words, patterns of shells set to explode above and below the enemy.

The bombers could change height to try avoid the barrage, however depending on circumstances it might not be possible. For example, in large formations, it was not possible for planes to change direction or height quickly due to the danger of collision.

When the bomber formation was on the bomb run, it could not change direction because the bomb pattern would be messed up. If you abort the bomb run you have more problems the second time, so normally they tried to bomb on the first run.

Later in the war, the proximity fuse was invented by the British, and increased the effectiveness of AA fire a lot. It was put into production by late 1942.

why dont the current army ( or atleast post 1942 ) apply same idea with their tanks and stuff with computer calculated fuse? and fire flak into buildings they suspect
have snipers or hidden troops?

I've seen videos of some weapons (grenade launchers) where they do have smart fuzes. You shoot the grenade through a window and it's smart enough to know when it's inside, to explode where the frag effect is the most effective.

Those operate on timers. A laser will measure the distance, then the grenade is programed to explode at that distance before its fired.

Most modern missiles have their own radar or IR sensors that they use to determine how close to the target they are and detonate at the correct distance.

Of course for tanks, a canister round is far more effective. Think 150mm shotgun.

If the target is a tank, it's relatively easy to hit because it is slow moving compared to the speed of a shell. You need to hit it as hard as possible, and penetrate the armour.

If the target is a building, it's very easy to hit.

Shells which have to penetrate armour and explode inside can be easily be equipped with fuses with a very short time delay which activates once the target hits something.

In other words, the shell hits the window, or armour, and explodes a small fraction of a second later, when it will have passed through the obstacle. Such fuses were in use in WW1, for firing against armoured ships.

Modern fuses are timed not to activate until they have got far enough from the gun to explode without hurting the firer. They are also set to explode by the time they finish their flight, to avoid littering the landscape with unexploded fuses.

Artillery shells, and aerial bombs, are fitted with fuses that explode before they reach the ground, otherwise they bury themselves and do less damage. One of the things that helped the British army at Dunkirk was that the German aerial bombs buried themselves in soft sand before exploding.

Bombs made to drop on airfields have what are called dibber fuses. They are designed to bury themselves fully before exploding, in order to do maximum crater damage to the runway surface.

Different sorts of fuses and warheads are used in missiles and rockets, which do not have enough velocity to penetrate armour by physical impact.

That's a VERY good question. Something that they stuggled with for years. Often they had NO way of knowing. Observer balloons at known heights helped during WWI, during WWII radar helped some. But usually FLAK did not work well at all. Hence the Allied Air Command thinking for a long time was "The bomber will be through".

GW re-rolls hits for Twin-Linked because to-hit is the first step in the process. This minimizes total die rolls.

It's purely mechanical.

How did they get that to work (ie, what mechanism)?

I just can't picture it.

The way it works is like this:

I have two guns. i shoot the first one misses, i shoot the second and that hits. get it?
I also think you should have a choice of weather you reroll or if you do Two shots, but i digress.

It has a tiny radio transmitter and receiver in it.

The shell's body acts as an aerial. As the shell approaches a reflective target, which could be an aircraft or the ground, an interference pattern is set up between the outgoing and incoming radio waves, and the fuse detects this.

The power, frequency and wavelength of the radio wave are known, and the interference pattern increases in amplitude as the shell approaches the target. This lets the shell know how fast it is moving and how far away it is from the target. The fuse can therefore be set to detonate at the ideal distance.

ya but, i sort of pictured as TL have the exact same aim... if one miss, wouldnt the
other barrel that fired at same spot miss too? ( im not debating, i know im clueless about all this lol
just trying hard to understand / picture it )

Realistically, twin linked weapons should really just allow you to have 2 shots. However, the re-roll misses rule is clever way to minimize dice rolls and also makes twin linked weapons slightly less powerful.

Generally re-rolling wounds/armor penetration is better than re-rolling hits as it's more difficult to score a meaningful result on the wounding/penetrating roll (4-5+ required) than the to-hit roll (3-4+ required). Likewise doubling the number of shots gets pretty sick as you're literally doubling the potential output of the weapon (Land Raider Crusader with 32 shots from hurricane bolters and assault cannon).

So it's more of a balance issue than anything else, really.

If you have a double-barrelled shotgun and pull both triggers at exactly the same time, both shots will hit (or miss) the same target.

However, the point of a double-barrelled shotgun is to shoot one barrel and quickly shoot the other without having to take your aim off the target. You can see if your first shot hits and shoot again if you missed.

That is why big game guns for shooting elephants and lions are double-barrelled.

OTOH, if they were made using a semi-automatic feed, they could be made as single-barreled.

Big game guns have been made in double-barrel, single-shot and bolt action. I think the reduction in big game hunting made the introduction of semi-auto weapons uneconomical.

(nvm)

Twin linked weapons - It's GW's answer to "How do I give players better chances to roll-to-wound their targets without giving them more chances to wound altogether?"

To that extent it was a balance issue.

An issue which has nothing to do with the armaments of a Land Raider Crusader.
