Call me a stickler for detail, but I couldn't help noticing that you have to research supersonic ammo in this game (v0.845 English), and under its description, supersonic ammo is illegal.
I assume this is a mistranslation - it's pretty far-fetched, especially given that anti-personnel mines *are* legal in the game. Nearly all firearms use supersonic ammunition, and subsonic ammo is a specialised tool used only by some snipers (supersonic bullets make a loud bang as they pass objects, which can give a sniper's position away). As a reference point, the old Soviet AK-47 has a muzzle velocity around 710m/s, which is about mach 2.1, and the M-16A2 has a muzzle velocity of about 930 m/s.
Can anyone shed some light on this?

With supersonic is meant a higher speed as sonic in a human body.

PS: Hope you could understand what I want to say, my english isn't so good ;D

Perhaps you could call it hypersonic? In an old CNN article I found the following definition: Hypersonic is defined as traveling at a speed equal to about fives times the speed of sound or greater.

(I can't believe I forgot to write down my password, so I'm again a GAST!)

Maybe it was a cookie thing or something as I appear to be automatically logged in now. Ah, that must be it as I posted my "hypersonic" suggestion from my laptop, not my main machine.

The speed of sound in air is about 340 m/s = mach 1
The speed of sound in a human body = about the speed of sound in water = about 1500 m/s = mach 4.4
The research description mentions bullets at mach 1.2, which, as the original poster pointed out, is slower than normal, not faster than normal.

You are right, if we speak about air. But if we speak about water, then you have:
water = about 1500 m/s = mach 1

Mach means the speed of sound in a medium. It is not a constant value.

I straight a few new things investigated and to me was noticeable that some weapons and types of ammunition possess a very strange description, therefore times kuz ne briefing:

Supersonic weapons (1.2 Mach):
You of the cell shock weapons heard, I are not not safe surely me, which exact specifications possess these weapons, but they move at substantially higher speeds, perhaps even in the hypersonic range (V>Mach 6). The G36 was originally conceived as cell shock weapon, whereby they are to have made however some changes, after these weapons were outlawed.
No rifle (perhaps still the front loaders) has an exhaust velocity in the subsonic region. The MG3 possesses an exhaust velocity of approx.. 900 m/s and the G36 one of 920 m/s. To the comparison the sound possesses a speed of approx.. 330 m/s.

Uranium ammunition:
It is conscious to me that the Russians and the Americans begin with larger calibers uranium nuclei, but with smaller calibers me nothing such is well-known. The additional mass, believes I, only with armor-piercing shaped-charge fuzes used. These projectiles obtain their effect by a charge, which is trapezoidally arranged, in order to produce as high a pressure as possible. Thus the explosive effect can be multiplied.
The art off coat is to be survived with the projectile unreasonably, since this coat does not have Chanche, the flight and the recoil only to a small part by the projectile is caused. The catch (the part, which adjusts the cartridges and which firing pin contains) is rather responsible for the recoil. With the MG3 specially a recoil amplifier exists, it to the catch makes itself possible fast to move and a high firing frequency to achieve. The G36 against it is a gas pressure loader, with which a part of the gas pressure is removed, in order to lead the catch "gently" back. The G36 is called also recoilless, since the recoil with that of of a strong is luftgewehrs to comparisons (recoilless [ probably because of the projectile ] is thus not whole), while the mg can break the shoulder, if one does not against-lean correctly.

Waers first times!

A translation of my text. *lol*

it won't me edit the name to you altfelde, but yes I took a look at your name translated and it is yours, I posted it becuase you sound more knowledgable than anybody who speaks in this subject. online translators are pretty cool, i know more because of it like the increeased resolution for 9.0 and what not.
