Tank/APC/50 Cal Bullet Drop

[[uBp]Irish]

well. irl, .50 cals are pretty devestating.

you point it, and the just shear amount of dmg it can put out, probably warrants the fact that you should be getting 12 kills with it before you die.

Again, you must take into account not the effectiveness of the weapon and the user, but the stupidity of the people on the other end.

As soon as someone can figure out how to make something work, and someone on the recieving end dies via that new ability, that guy is now going to get all pissy and start crying because he cant have "fun" in "his" game.


and i believe cheesman's up-armored humvee(see the community mod section) has close to full 360 degree protection for the .50/240(i'm thinkin he's making a variant) gunner on top. Now the humvee will be a force to be reckoned with.

Lase systems cannot determine lead on a multi variable changing object, it's just not possible.

Helicopters can change course on all 3 axis' at a moments notice, there is no way the ballistics computer would be able to calculate that in time. It would literally have to steer the round in the air unless it could tell the future. The tanker has to adjust for lead, the ballistics comp just does the distance IIRC.

The ballistics computer can predict the future . If something is traveling in one direction then it tends to go in that one direction. The computer can use this fact to calculate the course of the the target and the predict the position of the target at the time the round would get there. As long as the target doesn't deviate from the position significantly(1) is and the environmental factors are properly accounted for then the round should hit.

(1) The amount of deviation per second required for it to be significant is inversely proportional to the distance (ie the further away the target is, the bigger the impact is from it moving off course) and of course, it is proportional to itself.

I think the main problem is that Sectornine assumes that the rangefinding laser only needs to hit a target once (aka for a tiny fraction of a second)
US tank gunners iirc are trained to lase a moving target for 1.5 seconds - that's 1.5 seconds where the laser is constantly held on the target as it moves regardless of the axes (if it's moving in a constant motion for that time, a modern tank will hit the target with ridiculously high accuracy out to 4000m) - so that the most accurate prediction can be made for the fire control
The tank is also measuring wind and atmospheric variables and the computer simply does the basic math - it all comes down to velocities and angles in the end, the basic trigonometry you learn in school

[RCMoonPie]

In RL, the majority of modern tank gunners just

1. Point at the target

2. Las the target, thus instantly calculating the distance and calibrating the coax accordingly.

3. Shoot


So with regards to tanks, what we have now models how effective coax fire would be in RL. With the exception of the ballistics curve....

Agree with 50's perhaps being zeroed to a certain range.

I agree....but that is on a still target on the ground....
what if the target is in the air....and moving....therefore having to be led?
If you are leading an air-target....you are pointing off into the "blue"....how can a range be lazed if you have nothing for the lazer to bounce off of?

A 1500 m/s round (from a C2, incidentally) does not give a chopper much time to bank out of the way, you just start turning and then get hit.

At 1000m it takes (ignoring drag) 0.67 seconds to hit.

The tank is good at AA because the shell should drop 6.5m during flight but doesnt drop at all also the turret movement and firing is instant.

[Sabre_tooth_tigger]

60% of 10 basically?

Yea the computer cures all ills but the turret moves too fast if they (could) put in the drop I'd be happy tbh

[Sabre_tooth_tigger]

Which equation is that? Its only 2 metres then but enough to muddy the waters hopefully, I do think kashan with its view distance is lobsided in its realism because of this factor maybe, or whatever it is it does not play right. Maybe it needs heat haze or something to make it less 'perfect'

[Sabre_tooth_tigger]

opps basic equation, think I remember it from like 20 years ago, roughly

The problem with kashan is the view distance, its way too small and should be around 2km with the bf2 fog evenly distributed instead of starting at 700m and ending at 980m. Just look at the fog on fools road, it looks a lot better because of it starting at 0m.

Sounds good. I cant say Ive noticed the fog on fools road massively but I dont tank or apc often on that map so I'll take a look. Kashan makes it more obvious because there is no trees, etc which is fair enough when its a desert I guess :/
