Gun laws in Cyberia

Cyberian gun licenses and gun classifications are determined only by their average muzzle energy, which is officially measured in joules. Other aspects such as the action of the firearm or the capability of self-loading (semi-auto and/or fully-auto) do not apply.

Muzzle energy is the kinetic energy measured at the muzzle (precisely, one projectile length from the muzzle), calculated by this formula: Ek represents kinetic energy in joules. m represents projectile mass in kilograms. v represents projectile velocity in meters per second.

Gun Licenses
Gun licenses are required to buy and own firearms in Cyberia. Those who attempt to purchase a firearm without a license are immediately turned away. Those who are in possession of a firearm while unable to present a proper government-issued license are to be immediately detained.

Class IV
This class of gun license allows the use of anti-tank and anti-matériel rifles.

Class IV firearm licenses require: Class IV license holders are able to:
 * Previous ownership of a Class III firearms license.
 * Most strict recurring background checking.
 * Own and purchase Class IV firearms (muzzle energies greater than 10,000 J and less than 65,000 J).

Class V
Class V is the highest class of firearm license available to civilians in Cyberia. This class generally allows the use of small-bore cannons. This class is special in that owners can only operate cannons with calibers less than 60mm.

Class V firearm licenses require: Class V license holders are able to:
 * Previous ownership of a Class IV firearms license.
 * Most strict recurring background checking.
 * Own and purchase Class V firearms (muzzle energies greater than 65,000 J and less than 60mm in caliber).

Class M
Class M is NOT available to civilians, as it is separate from the other classes, and is reserved for military personnel and the honorably discharged. The "M" is not a roman numeral 1000, rather it stands for "Military".

 * Specialized familiarity and training with large-bore cannons.
 * Current or previous employment by the CMF.
 * In the case of previous CMF employment, an honorable discharge.
